To address the problem that piezoelectric energy harvesters are difficult to apply in certain environments. this paper establishes the theoretical study of the intermediate fixed disc piezoelectric energy harvester (IFDPEH) based on the unimorph under concentrated force. The reliability of the model was indirectly verified by numerical simulation and Computer-Aided Engineering (CAE) s... https://pandaesfoxtoyes.shop/product-category/clearance/
