Piezoelectric road technology is an emerging method of harvesting electrical energy from moving vehicles by converting mechanical stress into usable power. With increasing urban energy demand, transportation infrastructure can serve as a continuous renewable energy source. This review examines the working principles, materials, installation techniques, and performance characteristics of piezoelectric road systems reported in previous studies. Various research findings on energy output, sensor placement, traffic loading effects, and durability are compared. The advantages of clean energy generation, reduced transmission loss, and smart city applications are discussed. Key limitations such as high initial cost, maintenance requirements, and low conversion efficiency are also analyzed. The study identifies research gaps related to material improvement and system optimization. It concludes that piezoelectric roads can function as a supplementary Eco-friendly energy solution when integrated with advanced technologies.
