MIT has developed a way to wirelessly read vitals signs through walls

MIT’s rather fabulous Computer Science and Artificial Intelligence Laboratory, after using humble WiFi waves to sense movement behind a wall, has now improved its technology to the point that it can remotely detect heart rate and respiration through walls. MIT has successfully used this technology to non-invasively check a sleeping baby’s breathing and pulse, and even to track the breathing of two adults simultaneously. This time last year it was Wi-Vi, but with some further refinements, MIT is now calling it WiZ. While Wi-Vi and other similar technologies could detect movement in general, WiZ can use radio waves to accurately locate up to four people in a room.
