MIT Computer Science and Artificial Intelligence Laboratory researchers recently developed a tech piece that can help search and rescue teams and parent.

Using a low power Wi-Fi signal as a “sonar” has enabled the MIT team to measure the rise and fall of a participants chest movement and determine heart rate with a 99% accuracy. The system can track up to four people at a time.

“It has traditionally been very difficult to capture such minute motions that occur at the rate of mere millimeters per second,” paper co-author Dina Katabi said in a release. “Being able to do so with a low-cost, accessible technology opens up the possibilities for people to be able to track their vital signs on their own.”

A few applications could be baby monitoring, search and rescue scenarios and track your own health statistics..

In the future? The MIT team is now interested in expanding it so it can be used to track emotion, which is also linked to heart rate and breathing.
