To hear a pitter patter from afar: Catching heartbeats with millimeter-wave radar

Heartbeats can now be measured without placing sensors on the body, thanks to a new technology developed in Japan. Researchers at the Kyoto University Center of Innovation, together with Panasonic Corp, have come up with a way to measure heartbeats remotely, in real time, and under controlled conditions with as much accuracy as electrocardiographs.

The technology utilizes spread-spectrum radar to catch signals from the body and an algorithm that distinguishes heartbeats from other signals.
