Mandar Tulankar, a student at Nuva College of Engineering in India and founder of Angels R&D Pvt Ltd., invented the mobile shoe charger that uses the pressure created by walking to power cell phones. “The mobile shoe charger“ which is based on the concept of converting pressure to electricity using PIEZO crystals through piezoelectric effect can end your phone’s battery life woes. The charger is present in the sole of the shoe and as soon as the person wearing the shoe starts walking, the charging will start. The charger has nearly zero maintenance, has easy assembly and handling and is highly affordable to different sections of the society.
