Biological Sensors and Multiorgan Diagnostic Screening Physiographic Personnel Monitor

Abstract

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 meter or more frequencies of 220 - 420 MHz. Electronic interface units were constructed that contain the circuitry necessary for opto-electronic conversion as well as to perform the sum and difference calculations to isolate the heartbeat-related changes in the sensor's output signal. A laptop-based A/D) data acquisition system was implemented.
