Design and development of flexible piezoelectric/magnetostrictive composite materials and development of energy harvesting IoT systems

今年，我继续研究用于能量收集的柔性压电复合材料。利用钛酸钡(BaTiO3，BTO)和聚偏氟乙烯-三氟乙烯(P(VDF-TrFE))共聚物制备了一种功能梯度的柔性压电材料。新的生产方法使弯曲过程中的输出电压提高了15倍，品质因数(FOM)提高了3.2倍。本研究提出了一种利用压电材料从人体运动中提取能量的新方法。我根据这些发现撰写了一篇学术论文，并将其提交给一家学术期刊；手稿目前正在进行审查。此外，我还参加了国际和国内的会议，并向其他研究人员介绍了这项研究的最新发现。

This year, I continued to study the flexible piezoelectric composites for energy-harvesting. Barium titanate (BaTiO3, BTO) and poly (vinylidene fluoride-trifluoroethylene) copolymers (P(VDF-TrFE)) were used to create a functionally graded, flexible piezoelectric material. The new production method increases output voltage during bending by 15 times and increases figure of merit (FoM) by 3.2 times. This study proposes a novel method for utilizing piezoelectric material to extract energy from human motion. I composed an academic paper based on these findings and submit it to a academic journal; the manuscript is currently undergoing review. In addition, I have attended international and domestic conferences and presented the most recent findings of this study to other researchers.
