Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory (CSAIL) has developed a wireless device that is the size of a small painting and could help diagnose cognitive decline and cardiac disease – all through wireless signals.

The device, deemed WiGait, measures the walking speed of people with 95 to 99% accuracy using wireless signals while hanging on the wall of a person’s home. The signals emit nearly one-hundredth the amount of radiation that a standard cellphone emits.
