Development of wear-free health monitoring system for independent aged people
Hitoshi Ueno · 2016
Proposed monitoring systems do not need to put sensors on the human body to recognize normal or abnormal status in senior citizens. Conventional wear-free monitoring systems use live cameras or home electrical appliances, but they have problems of privacy or habit dependencies. Also, wearable monitoring systems have problems of inconvenience for a user's life style. Our final objective is to provide a monitoring system using sheet-type piezoelectric sensors, which can sense even if the wearer is lying or sitting on the floor, bed or chair. The sensor data will be sent into care management cloud systems, and if those sensors find abnormalities in the status of care recipients, notification email will be sent to care givers. This research shows an implementation of the trial system program that has primary functions. It receives signals from a piezoelectric sensor and extracts cardiac cycle and respiration cycle signals using particular digital filtering steps.
