Older people have expressed a clear desire for unobtrusive wearablemonitoring devices. Emerging batteryless sensor technologies suchas sensor enabled RFID (Radio Frequency Identification) create newopportunities for building unobtrusive wearables for older people.This study aims to: i) uncover user perceptions and acceptability ofa batteryless wearable sensor concept for hospitalized older people;and ii) present the construction of anewtextile integrated wearablesensor incorporating user feedback. We recruited 40 older people(age: 81.0±7.0 years) to wear our initial sensor prototype and usedtwo modified versions of validated questionnaires to evaluate userperceptions and acceptability. Our results showed: i) allowing olderpeople to experience the system created the opportunity for themto develop confidence and trust in the sensing technology, evenwhen they were initially anxious and skeptical: and ii) the firstdesign prototype should ideally be modified to reduce its visibility.To this end, we built a new wearable sensor design.
