MIT's WiFi System Detects People's Breathing, Heart Rate, Even Through Walls

Seeing through walls has been a fantasy for many of us since childhood, but while the rest of us grew up, researchers at MIT are now doing things previously thought impossible. While they still don’t have the technology to literally see through walls, researchers of the NETMIT group at MIT’s Computer Science and Artificial Intelligence Lab, are using WiFi signals to detect the breathing and heart rate of individuals in a room. They’ve just released a couple videos showing off the technology in action:

Here’s a demo of a child’s respiratory rate and heartbeat being detected from the captured WiFi signals bouncing around the room.


An example of the system, placed in an adjacent room, monitoring the breathing rate of two individuals at the same time:
