Meet the Sleepman: a smart wearable device that tracks your sleep and keeps you from drowsy driving. It wakes you up at the right stage, so you feel more energized. The device warns drivers of concentration loss on the road with visual alerts.
Sleepman can also check your heart for arrhythmia. There is even a panic alarm that lets you get in touch with your loved ones when in trouble. This project is currently active on Kickstarter.
