Power generation transducer from magnetostrictive materials

In this letter, on the basis of Stoner-Wohlfarth model, the changes in magnetization of Tb(0.3)Dy(0.7)Fe(2) alloy have been calculated with a compressive stress along the [111] and [112] axes. The results have shown that the significant change in magnetization for Tb(0.3)Dy(0.7)Fe(2) alloy can be induced by the compressive stress. A feasible application of power generation floor which can convert the energy from the vibration created by a walking person on it into electric energy has been proposed, and its structure and performance also have been revealed.
