Abstract
Power harvesting from traffic-induced vibration of highway bridges is investigated in this paper. PZT (lead zirconate titanate) material is studied as the major piezoelectric element for power generation. Three mechanisms (PZT patch, cantilever beam and PZT stacks/slugs) are described that are suitable for a remote sensor system to scavenge mechanical energy at different locations in a bridge. A girder bridge model has been developed in ANSYS and its dynamic performance is studied by simulating a truck moving across the bridge at 60 mph. Power generation from piezoelectric transducers is then calculated based on the simulation results. Finally the predicted power generation is compared to solar/light power, one of the most common sources of power in the ambient environment.
