Experimental analysis of vibrations damping due to magnetostrictive based energy harvesting

The paper deals with the mechanical vibrations damping effect induced by a magnetostrictive energy harvesting device properly working. The proposed experimental setup allows us to investigate, through time-domain measurements, the dependence of the mechanical damping from parameters like magnetic bias and external load, affecting the global harvested power. This result would underline the promising possibility to reduce mechanical vibrations and obtain power harvesting at the same time. (C) 2011 American Institute of Physics. [doi:10.1063/1.3545798]
