CARDIALARM

We build a device/application called CARDIALARM. The goal of the project is to create an alarm clock which wakes a user up during light sleep (a.k.a. REM sleep).

The project was inspired by the iOS app: 'Sleepcycle', which uses accelerometer data to determine if a user is in REM sleep. According to this 2011 study, a heart beat signal can be used to very accurately determine whether a person is in REM sleep. We decided to use heartbeat data rather than breathing data to determine if we could get a better analysis of REM sleep as well as record user data about when they sleep. We attempted to keep all components within a reasonable price range (as the competitor product is free) and were successful in prototyping the hardware with a total bill of materials under $25 (not including the Arduino—we would use a more specialized microprocessor in the real device).
