Design, Fabrication, and Test of a Coupled Parametric–Transverse Nonlinearly Broadband Energy Harvester

A coupled parametric-transverse nonlinearly broadband energy harvester utilizing mechanical stoppers has been designed, fabricated, experimentally tested, and in some cases theoretically verified. An energy harvester with coupled parametric and transverse cantilever beams with additional tip-masses was excited using an electrodynamic shaker. A piezoelectric bimorph has been attached to each cantil...
