Abstract
Since giant magnetostriction was first found at a room 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 in our daily life such as traffic-induced ground vibration or bridge vibration. We designed and fabricated a prototype of the generator. This report presents basic characteristics of the prototype and shows potential in practical use.
