1. Introduction

The 21st century is characterized by an inexorable demographic transformation, with global population aging reaching unprecedented levels. Projections indicate that by 2050, the number of people aged 60 years or over will double, reaching 2.1 billion, and the number of people aged 80 years or over is expected to triple to 426 million (United Nations, 2020). This demographic shift, driven by declining birth rates and increased life expectancy, places immense strain on traditional healthcare systems, social support structures, and economic frameworks. The imperative to sustain high-quality care while ensuring the independence and well-being of older adults has never been more pressing. Traditional caregiving models, often reliant on human caregivers, face significant challenges including a growing shortage of skilled personnel, escalating healthcare costs, and the emotional and physical burden on family members. These challenges necessitate a proactive exploration of innovative technological interventions that can complement human care, augment capabilities, and foster an environment where older adults can age in place with dignity and safety.

Within this context, on-body robots represent a pivotal technological advancement. These devices are more than mere assistive tools; they are sophisticated wearable systems designed to seamlessly integrate with the user’s body and daily routines, offering real-time assistance, continuous monitoring, and adaptive support. Characterized by their intimate physical proximity and ability to interact dynamically with users, on-body robots are at the intersection of several critical fields, including robotics, artificial intelligence (AI), sensor technology, gerontology, and human-computer interaction (HCI).

2.1. Design Principles and Features

On-body robots are meticulously engineered with several core design principles to ensure effective, intuitive, and beneficial interaction and assistance for older adults. These principles address both the physical and psychological aspects of user engagement:

• Co-presence and Embodiment: The concept of co-presence in human-robot interaction refers to the subjective experience of being in the same physical or virtual space as another entity, fostering a sense of shared environment and immediate connection (Biocca, 1997). For on-body robots, this translates into a tangible, physical presence with the user. Unlike stationary robots or remote monitoring systems, on-body robots are directly attached to or worn by the individual, creating an intimate sense of companionship and instant support. This physical embodiment allows for intuitive interactions, where the robot can directly respond to physical cues such as changes in gait, posture, or exertion levels, and provide tactile feedback through vibrations or gentle force application. The psychological benefit of embodiment is significant; a physically present assistant can reduce feelings of loneliness and provide reassurance, making the assistance feel more natural and less intrusive than a disembodied system. Advanced embodiment research focuses on developing robots that are not only physically co-present but also integrate seamlessly with the user’s body schema, becoming an extension of themselves rather than an external device. This involves careful consideration of weight distribution, flexibility, and ergonomic design to minimize discomfort and maximize the sense of natural augmentation.

• Multi-modal Communication: Effective communication is paramount for user acceptance and safe operation. On-body robots leverage a combination of visual, auditory, and haptic (tactile) feedback channels to communicate with users, catering to diverse sensory abilities and preferences, which are particularly important in an aging population where sensory impairments (e.g., hearing loss, visual acuity decline) are common. Visual cues might include LED indicators for status, small screens displaying information, or projected interfaces. Auditory feedback encompasses voice prompts, verbal instructions, alarms for emergencies, or soothing sounds. Haptic feedback, delivered through vibrations or subtle force feedback, can guide movements, provide warnings, or confirm commands without requiring visual or auditory attention, making it particularly useful for discreet assistance or in noisy environments. The integration of these modalities allows for redundant communication pathways, ensuring that critical information is conveyed effectively even if one channel is compromised. Furthermore, multi-modal communication enhances the overall user experience by making interactions more natural and less cognitively demanding.

• Adaptive Assistance: At the heart of advanced on-body robots lies their capacity for adaptive assistance. This capability is powered by sophisticated sensor arrays and artificial intelligence algorithms that enable the robots to continuously monitor a wide range of user data. These data include physiological parameters (e.g., heart rate, skin conductance, temperature, respiration rate), biomechanical data (e.g., gait patterns, balance, posture, limb movements, muscle activity), and environmental context (e.g., location, ambient temperature, proximity to obstacles). Advanced sensors such as accelerometers, gyroscopes, magnetometers, force sensors, electromyography (EMG) sensors, and even miniature cameras or radar modules are used. AI and machine learning algorithms process this continuous stream of data to develop a real-time understanding of the user’s physical and emotional states, activity patterns, and potential risks. This contextual awareness allows the robot to provide highly personalized and timely support. For instance, if the robot detects signs of fatigue or an unsteady gait, it can proactively offer increased support to prevent a fall. If it senses elevated stress levels or unusual inactivity, it can prompt the user or alert a caregiver. Adaptive assistance also extends to learning individual preferences and habits, allowing the robot to fine-tune its support over time, becoming more intuitive and effective. This dynamic adaptation ensures that assistance is neither too intrusive nor insufficient, striking a delicate balance to preserve user autonomy while enhancing safety.

• Materials Science and Miniaturization: A critical aspect of on-body robot design is the choice of materials. To ensure comfort during prolonged wear, designers utilize lightweight, flexible, and breathable materials, often integrating textiles with embedded sensors and actuators. Innovations in soft robotics are leading to devices that conform to the body’s contours, reducing bulk and improving range of motion. Miniaturization of components—sensors, processors, batteries, and actuators—is also essential to create devices that are unobtrusive and aesthetically acceptable. The development of advanced polymers, composites, and smart fabrics contributes significantly to achieving these goals, moving away from rigid, clunky machinery towards more natural, wearable extensions.

• Energy Efficiency and Power Management: Given that on-body robots are designed for continuous or frequent use, battery life and efficient power management are paramount. Innovations focus on developing low-power microcontrollers, energy-efficient sensors, and optimized algorithms that reduce computational load. Advanced battery technologies, such as higher energy density lithium-ion batteries and future solid-state batteries, are crucial. Research into energy harvesting techniques, such as kinetic energy harvesting from user movement or thermoelectric generators, also holds promise for extending operational times and reducing recharging frequency, enhancing user convenience and reliability.

2.2. Notable Examples

The landscape of on-body robots for elderly care is populated by several groundbreaking examples, each showcasing distinct approaches and capabilities:

• PECOLA (Personal Companion for Older People Living Alone): Developed by Taiwan’s Industrial Technology Research Institute (ITRI), PECOLA represents an advanced application of ambient intelligence and computer vision within a home environment to assist older adults, particularly those living independently. While not strictly ‘on-body’ in the continuous wear sense, its comprehensive system integrates wearable components (like fall sensors or smart watches that interact with the main system) with environmental sensors to provide a holistic support network. PECOLA employs high-resolution computer vision cameras, often strategically placed in a home, coupled with robust AI algorithms for continuous activity recognition, gait analysis, and anomaly detection. Its core functionalities include sophisticated fall detection through continuous monitoring of movement patterns and sudden impacts, health monitoring by integrating data from various biometric sensors (e.g., heart rate, sleep patterns), and proactive emergency notification systems that can alert designated caregivers or emergency services in critical situations. Beyond safety, PECOLA aims to enhance independence by offering personalized reminders for medication, appointments, and daily tasks, and by facilitating communication with family members. Its intelligent algorithms learn the user’s daily routines over time, enabling it to distinguish between normal activities and potential issues, thereby reducing false alarms and providing context-aware assistance. The system’s multi-modal communication capabilities often include voice prompts, visual displays, and remote caregiver access through a dedicated application, ensuring that older adults and their support network remain connected and informed (en.wikipedia.org).

• Elderly Bodily Assistance Robot (E-BAR): Conceived by engineers at MIT, the Elderly Bodily Assistance Robot (E-BAR) is specifically designed to provide direct physical support and active fall prevention, addressing a critical health concern for older adults: falls. Falls are the leading cause of injury-related deaths among adults aged 65 and older and a major contributor to morbidity and loss of independence. E-BAR’s innovative design consists of a set of robotic handlebars that subtly follow a person from behind, maintaining a constant, safe distance. This design allows the user to walk naturally without feeling tethered, yet provides an immediate source of stability. The robot employs advanced sensors, including LIDAR and computer vision, to accurately track the user’s movement, gait, and balance in real-time. If the system detects any signs of instability, a stumble, or the initiation of a fall, it can rapidly activate its robotic arms to provide robust physical support, gently guiding the user back to a stable position or catching them before they hit the ground. The control algorithms are designed to be proactive, predicting potential loss of balance rather than merely reacting. E-BAR also offers assistance with transitional movements, such as sitting down or standing up, where many falls occur. By providing ‘just enough’ support, it aims to preserve and even improve the user’s natural mobility and confidence, acting as a dynamic safety net rather than a passive crutch (news.mit.edu).

• HAL (Hybrid Assistive Limb): Developed by Japan’s Tsukuba University and Cyberdyne, Inc., the Hybrid Assistive Limb (HAL) is arguably one of the most recognized and advanced powered exoskeleton suits globally. HAL is a groundbreaking on-body robot designed to augment, support, and restore the physical capabilities of its users, particularly those with physical disabilities, neurological conditions, or mobility impairments. What sets HAL apart is its sophisticated control system that utilizes bio-electrical signals. When a person intends to move, their brain sends nerve signals to the muscles, generating minute bio-electrical signals (bio-electric potential) on the skin’s surface. HAL detects these signals via sensors attached to the user’s skin. Based on the strength and pattern of these signals, the robot’s onboard computer analyzes the user’s intended movement and activates its motors to provide synchronized assistance. This voluntary control mechanism means the robot moves in harmony with the user’s intention, rather than simply moving them, fostering active engagement and neuro-rehabilitation. HAL comes in various forms, including full-body suits, lower-limb systems, and single-limb variants, tailored for different applications. Its primary uses span rehabilitation therapy for stroke patients, spinal cord injuries, and neuromuscular diseases, as well as daily life support, enabling users to stand, walk, climb stairs, and perform other tasks that would otherwise be difficult or impossible. The system’s ability to provide adjustable levels of assistance makes it highly versatile for different stages of rehabilitation and varying degrees of physical capability (en.wikipedia.org).

• Soft Exosuits (e.g., Harvard Wyss Institute): Moving beyond rigid exoskeletons, significant research is focused on ‘soft exosuits’ or ‘exomuscles’. These devices, often made from textiles and flexible actuators, are designed to be lightweight, comfortable, and less restrictive than their rigid counterparts. They assist movement by applying force to specific joints or muscle groups through cables or pneumatic bladders, typically for walking or running assistance. Examples from the Harvard Wyss Institute have demonstrated soft exosuits that reduce metabolic cost during walking, making them ideal for individuals with mild gait impairments or those who experience fatigue easily. These suits typically use inertial measurement units (IMUs) and force sensors to detect gait phases and provide targeted assistance, mimicking natural muscle function.

• Smart Clothing and Wearable Sensors: While not always ‘robots’ in the traditional sense, smart clothing integrates sensors and sometimes actuators directly into textiles, blurring the lines. These garments can continuously monitor vital signs (ECG, respiration, temperature), detect falls, track activity levels, and even provide haptic feedback for posture correction or navigation. Companies like Hexoskin and Sensoria have developed smart shirts and socks that offer continuous physiological monitoring, providing invaluable data for preventative care and early detection of health decline.

2.3. Technological Challenges and Innovations

Despite the remarkable progress, the widespread adoption of on-body robots is contingent upon overcoming several significant technological hurdles, which are actively being addressed by ongoing research and innovation:

• Battery Life and Power Management: The most critical challenge for any wearable electronic device is power. On-body robots, with their multiple sensors, processors, and potentially powerful actuators, demand substantial energy. Ensuring prolonged operational time—ideally 24/7—without frequent, cumbersome recharging is crucial for user convenience, safety, and reliability. Current innovations focus on:

  • High-Density Batteries: Advancements in lithium-ion (Li-ion) chemistry, and the future promise of solid-state batteries, aim to pack more energy into smaller, lighter form factors.
  • Wireless Charging: Inductive or resonant wireless charging technologies could allow for ‘top-up’ charging throughout the day without direct physical connection, such as when a user sits near a charging pad.
  • Energy Harvesting: Research into harnessing kinetic energy from human movement (e.g., walking, breathing), solar power, or even thermoelectric generators (converting body heat to electricity) could provide supplementary power, extending battery life.
  • Intelligent Power Management: Dynamic power management algorithms that optimize power consumption based on task requirements, sleep modes, and predictive usage patterns are essential to maximize operational duration.

• User Interface and Interaction (HRI): Developing intuitive and accessible interfaces for older adults presents unique challenges due to potential age-related changes in cognitive function, dexterity, vision, and hearing. An overly complex interface can lead to frustration, errors, and rejection of the technology. Innovations include:

  • Natural Language Processing (NLP): Voice-controlled interfaces allow for intuitive interaction, especially beneficial for users with limited dexterity.
  • Gesture Recognition: Simple, clear gestures can replace complex button presses.
  • Personalized UI: Interfaces that adapt to individual cognitive and physical abilities, offering customizable feedback levels (e.g., larger fonts, louder audio, stronger haptics).
  • Explainable AI (XAI): Making the robot’s decisions and actions transparent to the user can build trust and reduce anxiety, especially when providing adaptive assistance.
  • Augmented Reality (AR): Potentially integrating AR overlays to provide contextual information or guidance without obstructing the user’s field of view.

• Safety and Reliability: On-body robots operate in close proximity to vulnerable individuals, making safety paramount. Any malfunction or unintended action could have serious consequences. Addressing this involves:

  • Mechanical Safety: Designing actuators and mechanisms to prevent pinching, crushing, or entanglement. Implementing emergency stop features and ‘soft’ operating modes.
  • Software Reliability: Rigorous testing, robust error handling, and fail-safe mechanisms to ensure the robot behaves predictably and reliably, even in unexpected situations.
  • Environmental Perception: Advanced sensor fusion techniques (combining data from cameras, LIDAR, radar, ultrasonic sensors) for robust obstacle avoidance, navigation, and understanding of dynamic environments.
  • Cybersecurity: Protecting sensitive personal and health data collected by the robot from breaches and unauthorized access. Ensuring the integrity of the robot’s control systems against malicious interference.

• Comfort, Wearability, and Aesthetics: For long-term use, on-body robots must be comfortable, lightweight, non-restrictive, and aesthetically acceptable. Bulky, heavy, or stigmatizing designs will hinder adoption. Innovations in soft robotics, flexible electronics, and advanced textile integration are crucial here. The goal is to make the robot feel like a natural extension of the body or a discreet piece of clothing, rather than a medical device or a burden.

• Cost of Manufacturing and Deployment: Currently, many advanced on-body robots, especially exoskeletons, are prohibitively expensive for most individuals, limiting their accessibility. Reducing costs through:

  • Mass Production: Scaling up manufacturing processes.
  • Modular Designs: Using standardized components that can be assembled in various configurations.
  • Advanced Manufacturing Techniques: Leveraging additive manufacturing (3D printing) and automated assembly to reduce labor costs and material waste.
  • Subscription or Lease Models: Making the technology financially accessible through alternative acquisition models.

• Maintenance and Repair: Like any complex electromechanical device, on-body robots require regular maintenance and occasional repairs. Developing systems that are easy to diagnose, modular for simplified component replacement, and supported by accessible service networks is crucial for long-term user satisfaction and operational uptime.

3. Ethical Considerations

The integration of on-body robots into the lives of older adults, while offering profound benefits, simultaneously raises a complex array of ethical considerations that demand meticulous attention. These issues are not merely technological but deeply intertwine with human values, societal norms, and individual rights.

Many thanks to our sponsor Esdebe who helped us prepare this research report.

3.1. Autonomy and Agency

The fundamental ethical principle of autonomy asserts an individual’s right to self-determination and independent decision-making. On-body robots are designed to enhance independence by providing assistance, yet their very presence and capabilities can inadvertently create an ‘autonomy paradox.’ While they aim to empower users by compensating for physical or cognitive limitations, there is a legitimate concern that over-reliance on robotic assistance could diminish a user’s sense of control and agency. If a robot anticipates every need or intervenes too frequently, it may reduce opportunities for the user to make decisions, exert effort, or engage in self-care activities, potentially leading to a decline in self-efficacy and a sense of learned helplessness. This could affect their self-esteem, mental health, and overall quality of life.

Ethical design mandates striking a delicate balance between providing necessary support and preserving the user’s maximum possible level of self-reliance. This requires:
* User-Centric Control: Giving users ultimate control over the robot’s functions, including explicit on/off switches, adjustable levels of assistance, and the ability to override automated actions.
* Graduated Assistance: Robots should offer ‘least restrictive intervention,’ providing only the necessary level of support and encouraging the user to perform tasks independently whenever possible. This can be achieved through adaptive algorithms that detect the user’s capabilities and adjust assistance dynamically.
* Transparency and Explainability: Users should understand why the robot is offering certain assistance or making particular recommendations, fostering trust and informed consent rather than passive obedience.
* Promoting Activity: Designing robots that encourage physical and cognitive engagement, rather than just passively supporting, can help maintain or even improve user capabilities.

Ultimately, the goal is for on-body robots to be facilitators of autonomy, not inhibitors. Ethical frameworks in robotics, such as those proposed by the IEEE P7000 series, often emphasize human well-being and autonomy as core principles (umatechnology.org).

3.2. Privacy and Surveillance

On-body robots, by their very nature, are intimate data collection devices. To provide personalized and adaptive assistance, they continuously gather sensitive personal data, including detailed health metrics (e.g., heart rate, blood pressure, sleep patterns, gait analysis), activity levels, location data, and potentially even audio or video recordings of daily routines. This extensive data collection raises profound concerns about privacy, data security, and the potential for surveillance.

Key privacy issues include:
* Data Security: The risk of data breaches, where sensitive personal and health information could be accessed by unauthorized parties, leading to identity theft, discrimination, or exploitation.
* Data Governance: Who owns the data collected by the robot? Who has access to it? How is it stored, processed, and shared? Clear policies are needed to define data ownership and access rights for users, caregivers, manufacturers, and healthcare providers.
* Scope Creep: The potential for data collected for one purpose (e.g., fall detection) to be used for another (e.g., marketing, insurance risk assessment, surveillance by family members or state actors) without explicit consent.
* Transparency: Users must be fully informed about what data is collected, how it is used, and with whom it is shared. This requires clear, understandable privacy policies, not convoluted legal jargon.

Robust safeguards are necessary, including:
* Encryption: All data, both in transit and at rest, should be securely encrypted.
* Anonymization/Pseudonymization: Where possible, data should be anonymized to protect individual identities.
* Strict Access Controls: Limiting access to sensitive data to only authorized personnel based on the principle of ‘least privilege.’
* Compliance with Regulations: Adherence to stringent data protection regulations such as the General Data Protection Regulation (GDPR) in Europe and the Health Insurance Portability and Accountability Act (HIPAA) in the United States is critical.
* User Consent: Obtaining clear, informed, and explicit consent for data collection and use, with easy mechanisms for withdrawal of consent (umatechnology.org).

3.3. Emotional Attachment and Dependence

The sophisticated interactive capabilities and, in some cases, the human-like appearance or empathetic programming of on-body robots can lead to emotional attachment from users. While providing a sense of companionship and reducing loneliness can be a positive outcome, especially for those experiencing social isolation, it also raises ethical questions about the appropriateness of using robots to fulfill deep-seated emotional needs.

Concerns include:
* Authenticity of Relationships: Is a robot-human ‘relationship’ a genuine substitute for human interaction, or does it merely provide an illusion of companionship? Critics argue that such interactions, while comforting, lack the reciprocity, spontaneity, and depth of human connections.
* Hindering Human Interaction: Over-reliance on robot companionship might inadvertently reduce motivation for genuine human social engagement, potentially exacerbating social isolation in the long run.
* Manipulation and Deception: If robots are designed to elicit emotional responses, there is a risk of psychological manipulation, particularly if users are vulnerable or have cognitive impairments. The ethical principle of not deceiving users is paramount.
* Grief and Loss: If a robot is damaged, malfunctions, or becomes obsolete, users who have formed deep attachments may experience significant grief or distress, similar to the loss of a pet or even a human companion.
* Stigma: The perception that an individual needs a robot for companionship could carry a social stigma, implying a lack of human connection.

Developers must consider the psychological implications of designing robots that evoke emotional responses. The focus should be on how robots can facilitate human connections and interactions, rather than replacing them. This could involve using robots as communication hubs to connect with family and friends, or as tools to encourage participation in social activities, thus complementing human care rather than supplanting it (umatechnology.org).

Many thanks to our sponsor Esdebe who helped us prepare this research report.

3.4. Social Equity and Accessibility

The advent of advanced robotic assistance presents a risk of exacerbating existing social inequalities. High-end on-body robots are often expensive, making them inaccessible to individuals from lower socioeconomic backgrounds. This could create a ‘robot divide,’ where access to advanced care and enhanced independence becomes a privilege of the wealthy, leading to disparities in the quality of elderly care and potentially worsening health outcomes for underserved populations.

Addressing social equity requires:
* Affordability: Strategies to reduce manufacturing costs, explore public subsidies, insurance coverage, or innovative financing models (e.g., leasing, tiered service plans) to make these technologies more affordable.
* Universal Design: Designing robots that are adaptable and usable by a diverse range of older adults, including those with varying physical and cognitive abilities, cultural backgrounds, and technological literacy levels.
* Equitable Distribution: Policies that ensure fair and widespread access to these technologies, perhaps through public health initiatives or community programs.
* Training and Education: Providing adequate training and support for older adults and their caregivers to effectively use and integrate these robots into their lives, bridging the digital literacy gap.
* Cultural Sensitivity: Recognizing that attitudes towards technology, caregiving, and dependence vary across cultures. Robots must be designed and introduced in a culturally sensitive manner to ensure acceptance and avoid imposing external values (umatechnology.org).

Many thanks to our sponsor Esdebe who helped us prepare this research report.

3.5. Accountability and Liability

A critical ethical and legal challenge arises concerning accountability and liability when on-body robots cause harm or malfunction. In the event of an accident—for example, a fall that the robot failed to prevent, or an injury caused by a robotic malfunction—determining who is legally and morally responsible is complex. Is it the manufacturer, the developer of the AI algorithms, the healthcare provider who prescribed the device, the user, or the caregiver?

This complexity is amplified by the autonomous or semi-autonomous nature of these devices. Traditional liability laws, often designed for products with clear human control, may not adequately cover intelligent systems that make independent decisions. Clear regulatory frameworks are needed to establish:
* Responsibility for Defects: Assigning liability for manufacturing defects or software bugs.
* Operational Failures: Defining responsibility when the robot fails to perform its intended function, leading to harm.
* AI Decisions: Establishing accountability for decisions made by the robot’s AI that result in adverse outcomes.

Addressing these issues requires a multi-stakeholder approach involving legal experts, ethicists, engineers, and policymakers to develop comprehensive guidelines and regulations that ensure justice and protect all parties involved. This will be crucial for building public trust and facilitating widespread adoption.

4. User Acceptance and Psychological Impact

The ultimate success and widespread adoption of on-body robots in elderly care hinge significantly on their acceptance by older adults and their caregivers. Beyond technological prowess, the human element—how users perceive, interact with, and integrate these devices into their lives—is paramount. The psychological impacts, both positive and negative, warrant thorough investigation.

Many thanks to our sponsor Esdebe who helped us prepare this research report.

4.1. Factors Influencing Acceptance

User acceptance of new technology, particularly in a sensitive domain like personal care for the elderly, is a complex phenomenon influenced by a confluence of factors. Research models like the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAUT) provide valuable frameworks for understanding these influences:

• Perceived Usefulness (PU): This is arguably the most critical factor. Users are far more likely to adopt an on-body robot if they believe it will effectively assist them in daily activities, improve their health, enhance their safety, or otherwise bring tangible benefits. If a robot is seen as merely a gadget or an unnecessary complication, acceptance will be low. Perceived usefulness can relate to practical aspects like fall prevention, mobility support, medication reminders, or even psychological benefits like reduced anxiety and increased confidence in independent living.

• Perceived Ease of Use (PEOU): An on-body robot must be intuitive and easy to operate, especially for older adults who may have less experience with complex technology, or who face age-related cognitive or physical limitations (e.g., reduced dexterity, vision, or hearing). Clunky interfaces, complicated setup procedures, or frequent errors will quickly lead to rejection. Design elements such as natural language interfaces (voice commands), large tactile buttons, clear visual indicators, and minimal training requirements significantly enhance perceived ease of use. The learning curve should be gentle, and the interaction should feel natural and seamless.

• Trust: Building trust is fundamental. Users need to trust that the robot will perform reliably and safely, protect their privacy, and act in their best interest. Trust is cultivated through:

  • Reliability: Consistent and accurate performance of functions (e.g., accurate fall detection, consistent mobility support).
  • Predictability: The robot’s actions should be understandable and predictable, reducing anxiety.
  • Transparency: Users should understand how the robot operates, what data it collects, and why it makes certain decisions. Explainable AI (XAI) contributes significantly to this.
  • Competence: The belief that the robot is capable of performing its intended functions effectively.
  • Benevolence: The perception that the robot, or its developers, have the user’s best interests at heart (e.g., not collecting data for exploitative purposes). Lack of trust, particularly concerning data privacy and safety, is a major barrier to adoption.

• Social Influence: The opinions and experiences of significant others, such as family members, friends, and healthcare professionals, play a crucial role. If family members express concerns or support, it significantly impacts the older adult’s decision. Recommendations from trusted doctors or therapists can also strongly influence acceptance. Media portrayals of robots can also shape public perception and acceptance.

• Personal Innovativeness and Attitude Towards Technology: Individuals vary in their openness to adopting new technologies. Some older adults are early adopters and tech-savvy, while others are more resistant to change. A positive general attitude towards technology often correlates with higher acceptance. This factor is often mediated by prior experience with technology and the perceived benefits of technology in their daily lives.

• Cost and Affordability: As discussed in ethical considerations, the financial burden of acquiring and maintaining on-body robots is a significant practical barrier to acceptance, regardless of perceived usefulness or ease of use.

• Cultural Factors: Cultural norms surrounding aging, independence, caregiving, and technology can profoundly influence acceptance. In some cultures, reliance on technology might be seen as a sign of neglect, whereas in others, it is embraced as a means of maintaining autonomy.

4.2. Psychological Impacts

The introduction of on-body robots into the lives of older adults can elicit a wide range of psychological effects, influencing their emotional state, self-perception, and social interactions.

• Enhanced Confidence and Independence: One of the primary positive impacts is the boost in confidence and the preservation or enhancement of independence. By providing reliable physical assistance (e.g., reducing the fear of falling, aiding in mobility) or cognitive support (e.g., memory aids, medication reminders), robots can empower older adults to perform daily activities that might otherwise be challenging or dangerous. This renewed capability can reduce anxiety, foster a sense of mastery, improve self-efficacy, and contribute to a higher quality of life. For many, the ability to ‘age in place’ and maintain autonomy is deeply intertwined with their self-worth.

• Reduced Social Isolation vs. Exacerbated Loneliness: This is a dual-edged sword. For individuals experiencing loneliness, a robot with companionable features could potentially offer a degree of social interaction, reducing feelings of isolation. Features like programmed conversations, shared activities, or facilitation of remote communication with family can provide comfort. However, there is a risk that over-reliance on robot ‘companionship’ could inadvertently reduce genuine human interaction, leading to increased feelings of loneliness in the long run. The critical question is whether robots complement or substitute human connection. If the robot merely fills a void without fostering actual human relationships, it could mask or worsen social isolation.

• Identity and Self-Perception: Integrating robotic assistance can challenge an individual’s sense of identity and self-perception. For some, wearing an on-body robot might be perceived as a visible sign of decline or frailty, leading to feelings of embarrassment, stigma, or a diminished self-image. Others might struggle with the psychological shift of relying on a machine for tasks they once performed independently. Conversely, for some, the robot could be seen as an empowering extension of themselves, a tool that restores agency and capability, thereby enhancing their self-concept. The way the robot is introduced, its design, and how it is framed by caregivers and society will significantly influence this perception.

• Cognitive Load and Stress: While designed for ease of use, any new technology can introduce a cognitive load. Learning to interact with a robot, remembering commands, or dealing with unexpected behaviors can cause frustration, stress, or anxiety, especially for users with cognitive impairments. Constant monitoring, even if benevolent, can also lead to a feeling of being under surveillance, infringing on privacy and increasing stress levels.

• Physical Activity Levels: The impact on physical activity can be mixed. Rehabilitation exoskeletons and mobility assistance robots like HAL or E-BAR are explicitly designed to enable physical activity and therapy, which can improve physical health. However, if assistance is too pervasive, it could potentially reduce an individual’s motivation to exert themselves, leading to a decline in natural physical activity levels. The design must encourage active participation where possible, rather than passive reliance.

Understanding these psychological dynamics is crucial for designing on-body robots that are not only technologically advanced but also psychologically beneficial and ethically sound, contributing positively to the holistic well-being of older adults.

5. Applications Beyond Basic Monitoring

While basic monitoring of vital signs and activity levels forms the foundational layer of many on-body robot systems, their capabilities extend far beyond this, offering a sophisticated array of applications designed to address diverse needs of older adults. These advanced applications span physical, cognitive, social, and healthcare domains, enhancing independence and quality of life across multiple dimensions.

5.1. Mobility Assistance

Mobility is a cornerstone of independent living, and its decline is a major factor in loss of autonomy and quality of life for older adults. On-body robots offer transformative solutions for mobility assistance:

• Gait Training and Balance Support: Robots like HAL, E-BAR, and various soft exosuits are specifically engineered to provide physical support during walking, standing, and transitioning movements. They can assist in maintaining balance, correcting unsteady gaits, and reducing the metabolic effort required for ambulation. This is particularly beneficial for individuals with Parkinson’s disease, post-stroke recovery, or general age-related muscle weakness. By providing targeted force feedback or active assistance, these robots can help users relearn proper gait patterns, strengthen muscles, and reduce their fear of falling, thereby increasing their confidence and willingness to engage in physical activity.

• Fall Prevention and Recovery: Beyond proactive gait correction, some on-body robots feature rapid response systems that detect the initiation of a fall and physically intervene to prevent it, or minimize injury upon impact.
