You burn energy when you go for a run, but why not use that energy to power a light to help you run?! That’s precisely the idea behind the PIEZOLIGHT, a body-worn headlight that illuminates your path. The design harnesses energy from your steps using piezo elements located in the soles of your shoes to charge a battery that then powers the light. Never worry about buying replacement batteries- when one runs out, simply interchange it with the fully charged one from your shoes!
