Here's a variation of the Sleep Tracker Watch, the device that wakes you up depending on your sleep rhythms. The aXbo Sleep Phase Alarm Clock takes that design a step further, and substitutes a comfy sweatband-encased sensor instead of that clunky watch you have to wear to bed. The aXbo wrist band communicates wirelessly with its unusually-designed alarm clock/mother ship, telling it how much you've been tossin' and turnin', which apparently has something to do with your sleep phases. Once you reach a semi-wakeful state, the system decides to wake you up. This all happens within 30 minutes of that point of no return, the time you must wake up or you'll be late for work. You can also get an extra wristband for that significant other sleeping next to you, too.
