Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   In phase I, researchers will evaluate existing piezoelectric generation technologies in the laboratory and through mathematical modeling to optimize placement in pavement. In phase II, project site selections will be made for demonstration and evaluation purposes.
Goals:   The key project objective is to utilize piezoelectric generators embedded in the pavement to harvest electricity from the passage of traffic loads.
Field Test:   Yes
Product Type:   Research report
Technical report
Test Methodology:   In phase I, researchers will evaluate existing piezoelectric generation technologies in the laboratory and through mathematical modeling to optimize placement in pavement. In phase II, project site selections will be made for demonstration and evaluation purposes.
Expected Benefits:   The expected benefit is the demonstration of potential feasibility of proposed technology as an energy-harvesting source.
Deliverables: Name: Phase II report.
Product Type(s): Research report, Technical report
Description: The deliverable is a document summarizing the results of the phase II effort and recommendations for future research or implementation efforts.
Project Findings:   Harvesters provide very little useful power. Potential applications may include powering low-power lighting, switching, or sensors where power is not otherwise available. The harvesters may be used in conjunction with other sources, such as photovoltaic or wind turbines, to charge batteries for demand requirements. The project has already been used as a resource for efforts of the California Energy Commission as the only publicly available data source for comparison with vendor claims from other sources.
