One of the most challenging and important challenges faced in driving small electronics and wireless sensor networks is the construction of multimodal and multidirectional energy har-vester (EH) topologies with high-strain zones. The use of traditional cantilever beam EHs makes these shortcomings particularly significant. In order to overcome these challenges, ef-fective structural design is required. four distinct symmetric and asymmetric 3D skeletal structure topologies for energy harvesters are planned and presented in this article. The vibra-tional behaviour of the suggested structures is studied using the finite element method and compared to the corresponding cantilever beam. In addition, the electromechanical responses from the above EHs are collected indicating the advantages in more detail. The results sug-gest that the asymmetric frames can effectively overcome the major EH problems at the same time
