In 2020, I continued my research in magnetostrictive materials, especially focusing on the design of composite structures and improvement in magnetostrictive properties. A series of iron-cobalt composites were prepared in this study, including 1-3 and 2-2 models.In more detail, a 2-2 model iron-cobalt composite that bonds positive and negative magnetostrictive materials together, significantly improve the sensitivity and magnitude for the magnetic induction variation in response to the exterior bending or bias magnetization.On the other hand, a lightweight high-temperature iron-cobalt composite through embedding the iron-cobalt fiber into an aluminum matrix, exhibits a potential application in the high-temperature application.Besides, the evaluation of iron-cobalt magnetostrictive composite was examined both experimentally and theoretically. The finite element analysis was employed to analyze the distributions of the interior stress and magnetic induction, within both 2-2 and 1-3 composites. Moreover, on the basis of the theoretical model, a theoretical mechanism of mechano-magneto-electric conversion is obtained.This research provides insights into the design of efficient mechano-magneto-electric transductors or sensors, even energy harvesters.In 2020, my study has been published by an international journal (PPS-RRL). And another work is in major revision. On the other hand, I also give an oral presentation at an international conference.

在2020年，我继续研究磁性材料，尤其是专注于复合结构的设计和磁性特性的改进。在这项研究中制备了一系列铁 - 铜板复合材料，包括1-3和2-2型号。更详细地，一种2-2个模型的铁铜复合材料，将正面和负磁磁性材料粘合在一起，可显着提高磁性诱导的敏感性和幅度，从而通过对外部弯曲或偏置磁性剂的响应来启用磁性诱导。铁 - 铜纤维进入铝制基质，在高温应用中表现出潜在的应用。Besides，在实验和理论上检查了铁 - 铜磁磁体磁；使用有限元分析来分析2-2和1-3复合材料内的内部应力和磁诱导的分布。此外，基于理论模型，获得了机械杂志 - 电动转换的理论机制。这项研究提供了有关有效的机械机械磁铁转移器或传感器的设计的见解，甚至能源收获器，甚至是2020年，我的研究已由国际杂志（PPS-Rrrlllllllllllllll Lllllll）发表。另一个工作是重大修订。另一方面，我还在国际会议上进行口头介绍。
