Designing Test Machine for Piezoelectric Energy Harvesting from Pavement Deformation
Abstract:
To find the new type of sustainable and renewable energy and harvest energy from pavement deformation, a new idea of designing test machine to harvest piezoelectric energy from pavement is innovatively proposed. A mathematical model of open-circuit voltage is deduced from the piezoelectric equations. Design requirements of the test machine are proposed based on the model and vehicle driving condition. The construction and work principle of the machine are elaborated. A prototype of the test machine is designed and manufactured. Some experiment is done to test the excited voltage of a series of piezoelectric harvesters with the test machine. The result shows that the measured data are basically the same to the theoretical ones. It is feasible to use the test machine for measuring piezoelectric energy harvesting characteristics from pavement deformation. Therefore, the machine can be applied for in-depth and systematic studying piezoelectric harvesting energy technology from pavement deformation.
