Abstract:Piezoelectric energy harvesting technology is a promising strategy for powering wireless sensor networks. However, piezoelectric energy harvesters (PEHs), especially linear PEHs, usually have narrow operating frequency bandwidth. In this study, in order to broaden frequency bandwidth, a nonlinear multi-stable magnetically induced PEH array (MPEHA) with asymmetric potential wells is proposed. Specifically, the proposed MPEHA is consisted of piezoelectric energy harvesting technique, multi-resonance array techni… Show more
