WertelOberfel ESUB Tracks Smart Helmet features a self-adjusting fit system

When cycling, it’s important to wear a helmet to shield your head, but that’s not enough. It needs to be the correct size for your head to offer the maximum protection and avoid falling off. The WertelOberfel ESUB Tracks Smart Helmet comes equipped with a self-adjusting fitting system to keep you safe on the road. Once you close the chin buckle, an electric drive fastens the straps until the helmet is a safe, snug fit. The ESUB Tracks Smart Helmet uses a small Nano Arduino development board and a set of printed organic batteries to power these electronic components. Furthermore, the helmet features proximity sensors that monitor the area surrounding you. And, if a fast vehicle approaches, the helmet will vibrate to warn you, so you can move to safety. Finally, it also features light indicators, a microphone, and speakers to improve your safety and enjoyment when cycling.
