Piezoelectric tiles convert mechanical stress from footsteps into electrical energy through the piezoelectric effect, where pressure applied to certain materials generates an electric charge; when millions of people walk on these tiles in busy locations like Shibuya Station (approximately 2.4 million steps daily), the accumulated energy can power LED lights, digital displays, and sensors, demonstrating a practical application of renewable energy that transforms everyday human movement into sustainable electricity.
