Repairing process of a tire with embedded iron bars

These roads are embedded with special piezoelectric material that can collect kinetic energy from pedestrians' footsteps. When people walk, run or jump, the road surface is slightly deformed, creating mechanical pressure. Piezoelectric crystals convert this pressure into electrical energy. This energy can be used to illuminate street lights, power public displays, and even
