Piezoelectric Electricity Harvesting Method Using Road Bumps

Abstract

This paper presents an integrated into road bumps, targeting the capture of mechanical energy from vehicular motion and its conversion into electrical energy for sustainable transportation infrastructure. The system utilizes high-force piezoelectric stacks within a modular bump design, accompanied by efficient power conditioning circuits to store harvested energy. Field and laboratory testing validate the feasibility of powering EV-supportive infrastructure such as street lighting and IoT sensors. Performance analysis reveals micro-energy applications are viable, highlighting both advantages and limitations of piezoelectric road bumps as a supplementary green energy source.
