Experimental Assessment of Using PZT Elements for Power Harvesting in Roadway Pavement

This study describes the development of two piezoelectric prototypes capable of harvesting energy from the traffic on roadways. These systems utilize piezoelectric elements that respond to traffic-induced stresses. The prototypes developed involved various configurations of cylindrical piezoelectric elements. Traffic scenarios were considered for translating this power output into energy. The evaluation of the prototypes involves laboratory testing of their power output as a function of compressive stress, finite element (FE) simulation of their mechanical behavior and economic analysis of the value of the power being generated. The results available to date suggest that this technology shows promise in powering LED and low-watt sensors independently of the power grid.
