Bike helmets can help minimize injuries in the event of an accident, but could a helmet also be used to help prevent a crash, or even enhance your riding experience? ESUB Tracks from WertelOberfell attempts to do both, featuring a variety of electronic enhancements which are powered by photovoltaic cells wrapped around its outer surface.
ESUB Tracks includes a lighting arrangement on the back for turn signaling, triggered using voice commands to the helmet’s piezoelectric microphone. Additionally, it has a sensor to detect rapidly approaching vehicles from behind, warning the wearer of this condition via haptic feedback. Bone-conductive speakers are provided for listening to Bluetooth audio, and if all of that wasn’t enough, it even tightens down the straps when the buckle is fastened.
Overall control is accomplished using an Arduino Nano 33 BLE Sense, and you can see more of this amazing device in the video below.
