Abstract
Abstract
In this paper, the water catchment device is combined with the piezoelectric cantilever beam to gather raindrops into a larger rainball to improve the power generation efficiency of the system. This makes rainwater power generation more feasible. The results show that when the rainfall intensity is constant, the output voltage of the power generation system increases significantly as the size of the rainwater converging device increases. With the same size of rainwater converging device, as the rainfall intensity increases, the power generation effect is also significantly improved, thus demonstrating the feasibility of the new rainwater power generation device.
