@sanjifll on Instagram: "Japan is turning footsteps into electricity by installing piezoelectric tiles in high-traffic areas like train stations and public squares. These tiles use the piezoelectric effect, where mechanical pressure from footsteps generates a small electric charge that can power nearby devices like LED lights, digital displays, and sensors. How it works: The tiles contain piezoelectric materials that convert the mechanical stress of a footstep into an electrical charge. Where it
