It's about time that more options crop up for more sensitive wake-up alerts. The VAM Alarm Bracelet is an innovative idea that is ideal for couples with different sleeping schedules. Instead of emitting sound, this device pulsates gently, rousing only the one who wears it while he or she rests.
Yi-Hong Chou's nighttime accessory has been designed as a string of 24 bobbles with embedded LED lights that glow accordingly to indicate the hour of the set alarm clock. This time can be set with a smartphone app that communicates with the wrist-worn gadget by means of bluetooth. To charge the VAM Alarm Bracelet, simply separate it at its magnetized clasp and connect one end to a small USB adapter.
