Today's radar locates and tracks aircraft, measures the speed of fastballs and helps catch "lead foots." Most radar gather information from objects. However, researchers at the Georgia Tech Research Institute (GTRI) are exploring radar's ability to measure physiological data in humans. The new radar measures tiny movements of the human body caused by respiration and the beating heart. The Radar Vital Signs Monitor (RVSM) technology was originally designed for use during the Olympics to measure the vitals signs of athletes. RVSM technology, however, has other applications including law enforcement, telemedicine, heart disease screening, security and disaster search.
