Electronic engineers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), in Germany, have developed a reliable procedure, using radar, to detect heart sounds in lieu of a stethoscope. Using technology similar to traffic monitoring systems, a six-port continuous wave radar system measures skin vibrations whenever the heart beats. The radar system can measure wave changes in moving objects down to a few micrometers, which is necessary to diagnose small heart anomalies.

Researchers at FAU’s Institute of Electronics Engineering have developed a radar system which enables touch-free monitoring of heart sounds. The red beams show where the measurement is being made
