Abstract: The increasing demand for energy and the increasingly prominent environmental problems force people to seek clean energy in the environment. Presents a new arch energy harvester which can effectively utilize the vibration energy of waves. The feasibility of the arch vibration energy collector is analyzed from its working principle, and the calculation model of the harvester is established by Comsol, and the influences of cyclic loading action amplitude, excitation frequency, load resistance, piezoelectric position and base layer material on the piezoelectric performance of the harvester are analyzed to determine the optimal parameters of the harvester.
