Talk:Heartbeat Detector/@comment-75.81.54.102-20131126211548

I've heard that NASA recently developed a real-life heartbeat detector for search-and-rescue operations, called the FINDER (Finding Individuals for Disaster and Emergency Response). It's supposed to detect a human heartbeat buried beneath 30 feet of crushed materials, hidden behind 20 feet of solid concrete, and from a distance of 100 feet in open spaces.

Of course, NASA developed this device in collaboration with the U.S. Department of Homeland Security, so military purposes are sure to be close at hand.
