NASA heartbeat detection

This search and rescue technology by NASA found survivors buried under 10 feet of debris. The device, called Finding Individuals for Disaster and Emergency Response (or FINDER) listens for heartbeats and breaths of survivors trapped beneath 30 feet of rubble, within 100 feet in open spaces, or behind 20 feet of concrete. The microwave radar technology can find someone within five feet.
