Abstract

This paper deals with a new design of a thermo-magnetically activated piezoelectric generator. This proposed generator exploits the temperature-dependent magnetization of a ferromagnetic material, which is exposed to temporary change of temperature cycles. To promote a better understanding of the operation of this mechanism, a global coupled numerical model is presented, which is able to predict the static and dynamic behavior of the generator. It is shown that with some modifications to the physical design, the generator can be tuned for different activation temperatures. Energy densities of 280 and 67 µJcm were achieved by the proposed model of the generator for its opening and closing commutation, respectively.

摘要

本文介绍了一种新型热磁激活压电发电机的设计。该发电机利用了铁磁材料的温度依赖磁化特性，该材料会受到温度循环的临时变化影响。为了更好地理解该机制的运行，提出了一个全局耦合数值模型，该模型能够预测发电机的静态和动态行为。结果表明，通过对物理设计进行一些修改，发电机可以针对不同的激活温度进行调谐。所提出的发电机模型在其开启和关闭换向时分别实现了280和67μJ/cm的能量密度。
