Magneto-electric energy harvesting have been widely studied for the wireless sensor. magnetic field inducing strain in magnetic component, induced strain generates electric charge. We are surrounded with parasitic magnetic noise arising from various devices, but it is too small to harvest enough energy from these field. In order to improve the power-generating ability, ferrite was positioned at the front of cantilever structured magnetoelectric harvester. Measurements were made with changes in area, number, and position, etc. In this study, when two ferrites were vertically placed, peak to peak voltage with ferrite were two times larger than without it. |
