Heartbeat-detecting NASA invention saved four Nepal earthquake survivors


NASA technology sensed the heartbeats of four people trapped in rubble days after a huge 7.8-magnitude earthquake struck Nepal on April 25, saving the lives of the four men.

The new prototype technology — called FINDER (short for Finding Individuals for Disaster and Emergency Response) — uses microwave-radar technology to find people trapped under debris by sensing and locating their heartbeats. Two suitcase-sized FINDER prototypes developed by NASA and the Department of Homeland Security’s (DHS) Science and Technology Directorate were brought to Nepal to help with rescue efforts on April 29.
