<p>This paper maps the ethical concerns involved in using new technologies in the care of older persons by type of participant group and technology used. The study presents data from sixty-seven participants in total from three stakeholder groups (older persons, professional caregivers, and family caregivers) who relayed their opinions on three types of technologies: wearables, ambient sensors, and social assistive robots. The interview data collected was analysed using content analysis. Participants raised ethical concerns about user control, stigma, over-reliance on technology, isolation, deception, privacy breaches, and the replacement of human care. However, these concerns were not uniformly emphasized across participant groups, and not all concerns applied to each of the three technologies. Our findings revealed a reduced ethical sensitivity and preparedness for risk in the case of certain technologies. These ethical blind spots evident in our results pertained to privacy, stigma, and deception. With technologies continuously developing, such blind spots are a cause for concern.</p>
