使用压电材料将风能转化为低功率电力，使得为无线电子元件供电成为可能，特别是在强风地区。这项工作彻底探讨了纵横比（长度/宽度）对基于倒旗的压电能量收集器性能的影响。针对一系列电力负载进行风洞实验，以量化最佳功率输出。针对用于设计和优化此类新型可扩展风能采集器的多物理场系统的整体动力学得出结论。
The transformation of wind energy into low-power electricity using piezoelectric materials enables the possibility of powering wireless electronic components especially in high wind areas. This work thoroughly explores the effect of aspect ratio (length/width) on the performance of inverted flag-based piezoelectric energy harvesters. Wind tunnel experiments are conducted for a range of electrical loads to quantify the optimal power output. Conclusions are drawn regarding the overall dynamics of the multiphysics system for the design and optimization of this new class of scalable wind energy harvesters.
