Abstract: Harvesting energy has experienced a significant development in recent years, due to high demand on the mobile electrical devices and self powered systems. Thus, it is interesting to convert mechanical energy into suitable electrical energy using Magnetostrective materials. In this paper, a class of vibration energy harvester based on MsM (magnetostrictive material) is introduced and developed. The method used is strain energy that is straightforward and simple enough in comparison to others, such as finite element method. To analyze the MSM-based energy harvester, a beam equipped with Metglas 2605SC material wound by a pick-up coil has been considered. In order to power optimization a parametrical study has been performed and the results have been presented. The output power under base excitation can reach 9.4 mW which compete favorably with the piezoelectric vibration energy harvesters.
