Perceptions of Non-Invasive Wearable Technologies for Elderly Care: A Mixed-Methods Study on User Acceptance and Ethical Implications

he objective of this study is to analyze the acceptance and ethical conditions required for the implementation of non-invasive monitoring systems for older adults. Using a mixed-methods design, it integrates focus groups with older adults and a questionnaire with future social and healthcare professionals. The results show a high level of acceptance of wearable technologies that do not use cameras or microphones, highlighting their discreet nature, protection of privacy, and contribution to autonomy and safety. Participants valued person-centered design, transparency in data use, and technologies that complement—rather than replace—human support. The main perceived barriers were cost, lack of training, and the digital divide. These findings indicate that wearable devices can support aging in place when developed through participatory and ethical approaches that respect dignity and promote trust. The study concludes that successful implementation requires user involvement, clear communication, and sustainable strategies for integration into social and healthcare services.
