| Outline of Final Research Achievements |
We investigated potential of wave power generation using magnetostrictive material. The power generation system consists of plate of magnetostrictive element (Fe-Ga alloy) with coil wound, stainless yoke, permanent magnet, and free vibration inducing mechanism using desorption of permanent magnet. Here, the trigger forces are buoyancy of a buoy or rebound wave at quay. In former case, we demonstrated power generation by free vibration occurred by difference of buoyancy accompanied with up and down of surface of water. In latter case, we verified power generation by free vibration occurred by up and down motion of switching plate caused by the rebound wave. In both case, we succeeded to retrieve electrical energy of mJ order by single vibration enough to operate wireless sensor module.
