Abstract

This paper reports on a highly-efficient electromagnetic energy harvester for wireless and batteryless switches. The energy harvester relies on a central rotating magnet driven by magnetic launchers and combined with a ferromagnetic circuit to take advantage of nonlinear behaviors and to increase the electromechanical conversion efficiency. The experimental output energy reaches 1.235mJ (350µJ/cm³) with a conversion efficiency of 56%, making it one of the most powerful and the most efficient in the state of the art.
