Tracking Sleepers By Analyzing Radio Waves Around Them

Tracking Sleepers By Analyzing Radio Waves Around Them

An algorithm devised by researchers at the Massachusetts Institute of Technology can closely monitor sleeping patterns by analyzing radio waves reflected off the human body. The software, described in a paper presented this week at the International Conference of Machine Learning, measures frequency changes that occur when radio waves emitted from specialized sensors reflect off a person’s body. That could let anyone analyze their sleep patterns at home without wearing smart wristbands and rings to bed. “Our vision is developing health sensors that will disappear into the background and capture physiological signals and important health metrics,” said Dina Katabi, a professor of electrical engineering and computer science, who led the development of the home-router-sized sensors. Katabi, who co-founded home monitoring start-up Emerald , and her colleagues have been coming ...
