在过去的几十年里，磁致伸缩材料和所有多功能材料都受到了越来越大的技术关注。在文献中的几个贡献提出了用于体和MEMS器件的创新传感器和致动器中的上述材料。最近，磁致伸缩材料已经被提出用于通过利用所谓的Villari效应的能量收集应用。在这种情况下，压磁系数的行为和幅度是评估转换效率的重要因素。本文的目的是研究在受控条件下的商业Terfenol-D棒的压磁系数的实验行为。(C)2011爱思唯尔有限公司版权所有。
Magnetostrictive and all multifunctional materials have experienced in the last decades a growing technological interest. Several contributions, in the literature, propose the above-mentioned materials in innovative sensors and actuators both for bulk and MEMS devices. More recently, magnetostrictive materials have been proposed for energy harvesting applications by exploiting the so-called Villari effect. In this case, the behavior and the amplitude of the piezo-magnetic coefficients are an important element to evaluate the conversion efficiency. Aim of this paper is to study the experimental behavior of the piezo-magnetic coefficients of a commercial Terfenol-D rod under controlled conditions. (C) 2011 Elsevier B.V. All rights reserved.
