Designing Piezoelectric Harvesting Unit from Road Vibration

Abstract:

To open up a new way of green energy, the piezoelectric harvesting technology from road vibration is proposed. Research status at home and abroad is reviewed, some existed problems are pointed out. With the software of ANSYS, the arrayed space between piezoelectric vibrators and the material and thickness of substrate are chosen in the light of higher harvesting energy and better coupling properties. From the simulation results, can a unit of 280*280*20mm be determined. When it is embedded under 40mm asphalt concrete pavement, 1.785MW electric power can be harvested from each traffic lane and per kilometer. This shows that application of the piezoelectric harvesting unit has very nice optimistic prospects.
