Multi-sensor wireless physiological monitor module

A wearable, wireless, multi-sensor module for long-term, continuous physiological signal monitoring is presented in this paper. The multi-sensor wireless physiological monitor module, called a "tag", is attached to a wrist and a fingertip for monitoring skin temperature and beat-to-beat pulsation respectively, and the data is sent to a host computer, called a "reader", via a radio-frequency transmitter. Two major design issues are addressed: one is to combine the two sensors in one tag, and the other is to develop the low power consumption ASIC. It was verified through experiments that the tag module can monitor both the temperature and the pulse simultaneously in a long period, and the wireless transmission distance between the tag and the reader could be successfully extended to 6 meters
