Instead of jarring you out of bed at a random time in your sleep cycle which can make you feel groggy, the WakeMate wristband uses actigraphy to determine the ‘semi-awake’ arousal points in your REM cycle when waking can actually make you feel rested and refreshed. The wristband itself features a motion sensor to measure your body’s activity throughout the night, which correlates to your sleep cycles, and the information is sent to an application on your cellphone via Bluetooth.
Before you go to bed, instead of specifying an exact time to wake, you give the WakeMate software a 20-minute window in which you’d like to get up, and it will sound an alarm at the optimal time within that window. The WakeMate isn’t expected to be available until late January 2010 at which point it will sell for $49.99, but you can pre-order one on their site right now for just $5 down.
