Body Biosensor
From: NASA Tech Briefs Insider - 08/24/2006

University of Arkansas researchers have developed a wireless biosensor that
can record and monitor a football player's body temperature in real time. The
prototype designed by students in the College of Engineering contributes to
research into a commercial product that could prevent death due to heat
stroke. The complete system includes a thermocouple temperature sensor, a
transmitter, two amplifiers, and a base-station receiver connected to a
laptop with user interface software.  

The sensor, which was embedded in a Schutt football helmet, adheres to a
dense pad, which touches the surface of the player's forehead and records the
body's temperature from the temporal artery. The sensor sends an analog
signal to the transmitter, which converts the signal into digital data. The
connected components communicate with a base-station receiver, which
transfers data into a laptop computer. The system has a transmission distance
of approximately 1,000 feet, which would work in the largest football
stadiums.
