A comb-like beam based piezoelectric system for galloping energy harvesting

This paper proposes a comb-like beam (CombBeam) based piezoelectric energy harvester (PEH) for harvesting wind energy by exploiting the galloping mechanism. The CombBeam-based PEH consists of a series of parasitic beams being mounted to a conventional cantilever beam with a piezoelectric transducer. A theoretical modelling method is established to simplify the proposed CombBeam-based PEH as a multiple-degree-of-freedom (MDOF) system. The...
