A 15-year-old boy living in the Philippines has invented a shoe insole that produces electricity from the energy of every footstep — with the potential to charge small USB devices.

Angelo Casimiro constructed his device using piezoelectric materials, which can generate an alternating current voltage every time they are squeezed. He won a local award with his invention and earned a spot as a regional finalist in Goggle’s Science Fair 2014.

His project is Open Source and available for the DIY community to develop further. His research shows the device is perfect for powering “smart clothing” and blue tooth transmitters, and could potentially be improved to power USB devices and cell phones. His project are detailed on Instructables.com.
