AI device uses radio waves to track your sleep pattern

Sep 23, 2017, 6:26 AM EDT

As sleep disorders affect more than 50 million Americans, there is a pressing need for non-intrusive techniques to diagnose and study sleep problems. Researchers at MIT and Massachusetts General Hospital have engineered an AI-based device that ditches pesky wires and electrodes while using radio waves to monitor one’s sleep patterns.

The device is programmed to relate the changes in radio frequency, triggered by slightest movements like pulse or breathing, with levels of sleep, notes Smithsonian.com.

The machine learning algorithm picks physiological signals and other health metrics and analyzes them to gauge sleep stages, writes MIT News.
