Anchor Lead: You’ve probably heard that keeping a smart phone by your bedside can interrupt sleep, but there may soon be an upside to that habit.

Randy Atkins: What happens when you sleep can reveal a lot about your health, so Yingying Chen, of Stevens Institute of Technology, is developing ways for smart phone mics to recognize both obvious sounds of snoring or sleep apnea and even subtle movements like turning over to reveal…

Yingying Chen: …people’s sleep patterns and then find potential health problems such as possible depression and early signs of heart problems.

Randy Atkins: Yes, Chen says she can even detect tiny motions like heartbeats by analyzing WiFi signals in your house as they flow past you to the phone.

Yingying Chen: All of those kind of movements will affect the fine-grained WiFi signals.

Randy Atkins: Your smart phone likely already has the necessary hardware to do this. Chen says her downloadable software should be ready later this year. With the National Academy of Engineering, Randy Atkins, WTOP News.
