Remotely Vital Signs Capturer for Older Adults Applied in Residential Zones

Assisted technology combined with sensor networks is an emerging technology for better homecare of people requiring specific support. In this work, we focus our attention on monitoring vital signs and accident prevention of older adults in residential areas without invasive and uncomfortable medical devices. We prototyped two vital signal monitoring devices integrated in structures deployed in common areas such as an arch and a bench. In addition, an alarm system was implemented to monitor residents in common areas and prevent vehicle accidents. The system was tested using Zigbee and LoRa wireless technologies and the network's overall performance was compared. In addition, the proposal was compared to commercially available medical equipment and results show a 96% similarity in vital signs monitoring. The system offers a silent noninvasive operation together with a friendly user interaction. It allows caregivers and family members to monitor vital signs of the residents remotely without the need of wearable specialized devices.
