Japonya ayak seslerini elektriğe dönüştürmek için piezoelektrik fayanslar kullanıyor. Bu fayanslar ayak seslerinden kinetik enerjiyi yakalıyor. Yürürken ağırlığın ve hareketlerin fayanslara baskı yapar. Fayanslar hafifçe bükülecek ve mekanik stres yaratacak. Fayansların içindeki piezoelektrik materyal bu stresi elektriğe dönüştürüyor. Her adım küçük miktarda şarj yaratır ve milyonlarca adım birleşince LED ışıkları, dijital ekranları ve sensörleri çalıştırmak için yeterli güç üretir. Shibuya İsta
