An algorithm can use WiFi signal changes to help identify breathing issues

Dec 20 2022 by Engadget

National Institute of Standards and Technology (NIST) researchers have developed a way to monitor breathing based on tiny changes in WiFi signals. They say their BreatheSmart deep-learning algorithm could help detect if someone in the household is having breathing issues.

WiFi signals are almost ubiquitous. They bounce off of and pass through surfaces as they try to link devices with routers. But any movement will alter the signal's path, including how the body moves as we breathe, which can...
