Wind Power Conversion Performance of Capillary Driven Electrokinetic Generators

Keywords： capillary force , nanogenerator , electrical double layer , evaporation , heat and mass transfer

提出了一种毛细力驱动的新型纳米通道双电层发电系统,可以同时收集利用环境中的各种品位能量进行发电.从理论和实验两方面对该系统的风能利用特性进行了研究,实验结果与理论分析吻合.直径1.5 cm的发电装置,在0～15 m/s的风速下,实验最高发电功率达到了30 nW;通过进一步减小发电流道尺寸,理论最高功率可达0.39 mW.
