WakeMate is a wristband system you charge with USB which uses BlueTooth to connect with your iphone, android, blackberry. When you go to sleep, it monitors your sleep using actigraphy in order to wake you up during the REM portion of your sleep, or as close as possible to it, within the 20 minute band the system will wake you around your set alarm time. This should get you out of bed when you’re fittest.

It comes with loads of graphy analysis tools, which is fun, but best of all, only costs $49.99!
