Abstract

Herein, we introduce a concept of the magnetic lens, which were composed of high permeability ceramic ferrites, to enhance the output performance of Magneto-Mechano-Electric (MME) energy generator. The magnetic lens was found to enhance the output voltage of MME generator by concentrating the weak magnetic flux originating from the magnetic field sources onto magnetic constituents in MME structure. The feasibility of the use of the magnetic lens as a magnetic flux concentrator was first evaluated by using Finite Elemental Analysis. The simulation results are then experimentally verified by harvesting the weak fields originating from the Helmholtz coil. Depending on the configuration of magnetic lens, the output of MME was different. The MME generator with a magnetic lens composed of four ferrites exhibited enhancement of 288% and 125% over that of MME generator without a lens and with a lens composed of one ferrite, respectively.
