NASA technology located four trapped earthquake victims in Nepal, by detecting their heartbeats - Quartz

NASA technology located four trapped earthquake victims in Nepal, by detecting their heartbeats - Quartz: "A technology developed by NASA and the US Department of Homeland Security designed to save people trapped by debris in natural disasters has been used in the field for the first time. FINDER (Finding Individuals for Disaster and Emergency Response) lived up to its name, locating and saving four people trapped under rubble for days after the 7.8 earthquake in Nepal killed more than 7,000 people and injured countless others.
FINDER is a radar machine that sends a continuous microwave signal through the rubble, and can detect a human’s breathing or heartbeat (and distinguish it from the movement of an animal). It can locate people hidden behind 20 feet of solid concrete or buried beneath 30 feet of rubble, and the person doesn’t need to be conscious to be detected.
