An Array Magnetic Coupling Piezoelectric and Electromagnetic Energy Harvester for Rotary Excitation

The energy of rotating machinery exists widely in the environment. It is great significance to collect and utilize for sustainable development. In this paper, a novel piezoelectric electromagnetic harvester, which capable generating electrical under rotary excitation, proposed based on array magnetic coupling. working principle kind harvester analyzed. And output modeling developed results are simulated. Based experimental test platform built laboratory, characteristics tested. Results show that maximum power reaches 182 mW when excitation speed 120 rpm. Furthermore, both module can reach at
