Translation is:Japan is using piezoelectric tiles to convert people's footsteps into electricity. These tiles capture the kinetic energy of people walking. As people walk, their weight and movement exert pressure on the tiles, causing them to bend slightly and generate mechanical stress. The piezoelectric material inside the tiles converts this stress into electrical energy. Each step generates a small amount of charge, and millions of steps accumulate to produce enough energy to power LED lights, digital displays, and sensors. In high-traffic areas such as train stations, approximately 2.4 million people contribute energy to the system daily. This electricity can be stored or used immediately, reducing reliance on traditional energy sources and supporting sustainable urban infrastructure development. This method transforms everyday activities into practical renewable energy
