碩士 === 東海大學 === 資訊工程學系 === 103 === Taiwan has gradually entered its aging society. Her elderly population, including those who can freely move and those who require long healthcare in bed, is still increasing on a yearly basis. Generally, physiological data as the health indicators of an elderly can effectively reflect his/her health status which in turn shows whether he/she has fully satisfied with his/her everyday life or not. A healthcare sensor system for elderly is a sensing system that serves elderly people with a wireless physiological sensor area network (WPSAN for short) and physiological sensors (Bio-sensors) to monitor their healthy conditions. The sensed physiological data is transmitted to an interface server which in turn sends the data to a remote healthcare server or a healthcare cloud. Currently, the volume and weight of the interface server is often far beyond conveniently portable and is consequently inconvenient for an elderly to handily carry it. Therefore, in this study, we develop a wireless physiological sensor architecture which integrates a Wireless Body Sensor Network (WBSN for short) and sensors to sense physiological data for an elderly, and then transmits the data to a remote healthcare cloud through a smartphone. The system also classifies the receiving data based on individual's personal ID and types of sensors, and stores the classified data in a healthcare cloud, from which healthcare givers can monitor the physiological data of an elderly via a healthcare monitoring system, and then timely give suitable healthcare to the elderly when necessary. We also set up personal physiological thresholds for individuals since physiological thresholds for different people vary. Once an elderly’s physiological data is out of its normal range, an alarm will be triggered and an email or a short message will be sent to healthcare givers to attract their attention.
