Abstract :
In this work, a novel resonator consisting of two detachable mass-springs has been developed. Fitting analysis shows that a corresponding mathematical model exhibits quantitative similarity between the simulation results and experimental data. Simulation results show that an electromagnetic energy harvester using the proposed resonator also has a improved electromechanical conversion efficiency compared to both a conventional 1-DOF resonator and a fully attached 2-DOF resonator.
