A Measurement Methodology for the Characterization of a Compensated Nonlinear Energy Harvester for Vertical Operation

In this paper, a measurement methodology for the characterization of the mechanical and electrical behavior of a nonlinear vibrational harvester is discussed and demonstrated on a real case study. The harvester, here considered, takes advantage of a flexible beam in a snap-through-buckling configuration and a novel magnetic repulsion mechanism to compensate for the asymmetric behavior of the devic...
