I don’t know about others, but I always feel that whenever I’m in deep sleep, my morning alarm starts buzzing. Wish there was some kind of device which would know when to exactly wake me up. Seems like my prayers have been answered. Bio alarm clocks are amazing. They are designed to wake sleepers at the perfect time. The clocks detect brainwaves or body movements and are programmed to wake sleepers during light sleep, which occurs periodically through the night. Consumers who used Sleeptracker, which is worn on the wrist felt that they have already been awake for some time, and the clock just let them knows it.
Other bio-alarms are SleepSmart, a headband with circuits that detect brainwaves during sleep, and the aXbo Sleep Phase Alarm Clock, which is a wristband that reads body movements. Besides Bio-alarms, other innovative wake-up devices for the bedrooms are the Clocky, which has wheels that drive it around, forcing the sleeper to get out of bed and chase it. The Biobright alarm clock simulates a sunrise using a 60-watt light bulb.
