In this paper, a physiological signal measuring system is presented. This system consists of a MCU-data-controller, a RFID ring-type pulse/temperature sensor and a RFID reader, and a GPS. The physiological measurements obtained from the RFID ring-type pulse/temperature sensor and GPS data are transmitted by the developed data controller to the PC through either Bluetooth, ZigBee, or TCP/IP. The PC not only collects physiological measurements but also tracks the position of the monitored person in real time.
