I like this idea, quite a bit. It’s been a desire of mine to really hone in on what my sleep cycles are like so that I can sleep an as little as possible, but still be completely recharged. I’ve never really enjoyed the alarm clock, so if I had the opportunity to rouse myself when my sleep cycle most supported it, that’d be great!
I nabbed the following details from their website at http://www.thesleepwatch.com
Check it out:
 
“An innovative device designed to monitor your sleep cycles and awaken you at the optimal moment, leaving you refreshed and ready to start the day.
SLEEPTRACKER is ideal for anyone who wants to wake up alert and ready to start the day, such as frequent travelers across time zones, business people looking for that extra edge, students with fluctuating schedules, or busy moms who need to wake up easily. When you set the ALARM WINDOW, SLEEPTRACKER wakes you when you feel like you’re already awake — at one of those frequent times during a night’s sleep when you’re almost awake but usually drift back to sleep.”
