Twelve, versatile wrist worn pulse monitors were developed and delivered. A light, non-constricting band worn around the wrist is pneumatically coupled to a small electro-optical unit worn on the forearm. The forearm unit contains a fiber optic sensor, pulsed laser, photodiode, PIC processor, DSP, transceiver, antenna, memory, battery, and other parts. Physiological data is radioed to an RS-232 port on a standard IBM compatible computer. The computer switches the unit ...
The Phase I effort has established the feasibility of a heartbeat and respiration sensor with high sensitivity based on a fiber optic coupler that will fit within the dimensions of a wrist watch. Radio frequency transmission tests have demonstrated the feasibility of using a custom designed IC with on- board antenna and driver circuitry to transmit the sensor's low frequency signal to a receiver unit over a distance of one ...
