Since giant magnetostriction was first found at aroom temperature in early 1980s, there have been many applications proposed. This paper introduces a novel application which is able to generate electric power by utilizing a reverse transduction of the material called Villari effect. The generator uses vibration as a power source which is easily accessible(More)
