The Smart Wearable Shoe is a self-generating, modular footwear designed for children. It solves the need for external power in smart wearables by using a micro-energy harvesting module to generate electricity with every step. This design replaces traditional batteries, eliminating heavy metals and enabling a 95% recyclability rate. Its modular structure allows for upgrades and a prolonged lifespan of up to a century, promoting a circular economy and reducing waste.
