The pressure from walking deforms piezoelectric materials inside the tiles, creating an electric charge. Where it’s used Tokyo train stations (like Tokyo Station and Shibuya Station) have tested these tiles in high-traffic areas. The energy is used to power LED lights, displays, or sensors nearby. How it works
