When you walk, your weight and motion create pressure on the tiles. The tiles bend slightly, producing mechanical stress. Piezoelectric materials inside the tiles convert this stress into electrical energy. Each step generates a small charge, and millions of steps together produce enough power to run LED lights, digital displays, and sensors. In busy plac
