The field of harvesting electrical energy from ambient vibration has grown with rapid interest. Perpetual source of electrical energy can be extracted from structural vibrations. The paper deals with a technology for scavenging electricity from vibration using iron-gallium alloy. This alloy offers high ductile property and the effect of inverse magnetostriction is also quite high. In this paper, a bending type magnetostrictive prototype energy harvester has been considered. Volume of the used material is 7 × 2 × 42 mm. Forced & free vibration characteristics have been examined on this prototype. Maximum conversion efficiency of 49% has been achieved at input frequency of 30 Hz.
从环境振动中获取电能的领域已迅速引起广泛关注。可以从结构振动中提取永久电能。本文探讨了一种利用铁镓合金从振动中获取电能的技术。这种合金具有高延展性，其逆磁致伸缩效应也相当高。本文考虑了一种弯曲型磁致伸缩原型能量采集器。所用材料的体积为7×2×42毫米。已对该原型进行了强迫振动和自由振动特性测试。在输入频率为30Hz时实现了49%的最大转换效率。
