Wearable tech has done a lot to foster the rise of the “quantified self” space, but surprisingly few of these devices focus on enhancing our safety.

Now a new prototype system looks to harness the kind of heartbeat and respiration monitoring features present in some wearables to alert drivers as to when they are dozing off behind the wheel.

Developed by the Biomechanics Institute (IBV) in Valencia, Spain, the Heart and Respiration In-Car Embedded Non-Intrusive Sensors (Harken) system works by measuring the heart rate (via seatbelt sensors) and respiratory pace (via seat cover sensors) of the driver.
