Recent developments in wireless and sensor technologies can help create a smart home health care environment at low cost, allowing patients to have their physiological signs monitored while staying at home. This paper describes an ongoing project on the design and building of a wearable wireless sensor system to acquire data concerning physical activities of a person in need of medical care. A waist-mounted triaxial accelerometer unit is used to record human movements. Sampled data are transmitted using an IEEE 802.15.4 wireless transceiver to a data logger unit and passed to a PC for analysis. The architecture design, the prototype implementation, and initial validation tests of the monitoring system are presented.
