Sleep Analysis at Home

If you’ve ever wondered how much sleep you actually got during a restless night, a new home-use device may have the answer. Users sleep wearing a headband fitted with a sensor that monitors electrical activity in the brain. Physicians use similar data gathered from EEGs to diagnose sleep disorders, but EEG studies are usually conducted in dedicated sleep clinics. In the home device, the headband sends data wirelessly to a bedside unit resembling an alarm clock, which records and displays the user’s sleep patterns. The data can be uploaded to a website that allows users to track sleep statistics and gives suggestions for how to improve sleep.
