Japanese Oyo Corp. developed a handheld device that finds survivors buried under rubble.
Until now mostly dogs are used to find survivors after an earthquake, who are buried by collapsed buildings. Technology has still to catch-up in this area.
The device from Oyo detects humans who are still alive and breathing by detecting the faint electromagnetic waves that reflect back from their moving chests.
The device needs antennas placed on the surface. One antenna can search 1m2 and 4.5m deep. So several antennas need to placed at the disaster area. Oyo will ship the device this October for 7.5 million yen (~$65,600). Not sure if a trained rescue dog is that expensive.

A more affordable device like this could definitely save lifes around the globe. Right now Pakistan got hit hard by an Earth Quake. Lots of people and kids got buried under rubble.
