Germany based design firm werteloberfell, has collaborated with a group of material scientists in finland and france to introduce ‘ESUB tracks’, a smart, self-sufficient urban bicycle helmet. the innovative design incorporates electronic features to further improve users’ safety. with a set of flat printed organic photovoltaics wrapping around its basic form, the surface of the helmet is used to recharge the batteries to power all electronic components. The helmet by werteloberfell, CEA liten and VTT incorporates a selection of electronic features to make cyclists’ experience easier and safer. Proximity sensors monitor the area behind the user, so that if a fast vehicle is approaching from behind, left & right piezoelectric haptic actuators start vibrating to warn the cyclist. Also, all electric additions are controlled by a nano arduino board and are powered by printed organic batteries.
