Abstract
In this paper an electromagnetic vibration type energy harvester based on diamagnetic levitation system is designed, fabricated and tested. The structure and principle of the energy harvester are expounded and the output induced voltage analyses are performed by COMSOL Multiphysics 5.2 under vertical excitation. The output induced voltage of the coils under different excitation frequency is tested. The peak voltage is up to 268mV and the average output power can reach 62µW at 2.8Hz under horizontal excitation. Seven capacitors are charged respectively by the energy harvester, which sever as a temporary power source can light up an LED.
