Recently, one can observe increasing number of small devices or sensors in many applicationsthat have to be powered by an energy which can be extracted from surroundings. Simple energyharvesting concept from mechanical vibrations of magnetostrictive materials is based on linear beamwith external excitation. In this case, the beam under load vibrates, and experiences stress or strain.This changes the beam shape which causes direction of sample magnetization (Villari effect) thatcan be captured by external coil and transferred to electrical power. In general, the higher amplitudeof beam vibrations, the higher energy can be extracted from the system. This can be achieve in thevicinity of a resonant frequency. In this paper, we propose energy harvesting model based on linearmagnetostrictive (MsM) beam with external coil. We analyse different shapes of the beam withrespect to different resonant frequencies |
