The Silent Alarm Clock wakes you by the vibrative ring. This concept designed by Johan Brengesjo. "Each person wears a wireless rubber ring with an integrated vibration device that generates a tactile alarm, the snooze function is engaged by shaking your hand. However, each successive time you want to snooze, more movement is required, making sure you get to work on time. "
