摘要近年来，利用液滴与电介质之间的摩擦电性的液滴发电机（DEG）受到了极大的关注。DEG产生瞬时高功率密度，尽管其简单的金属/电介质/金属堆叠结构。在DEG中，液滴和电介质表面之间的接触面积影响输出特性。我们使用PTFE膜作为电介质材料制造了DEG，测量了输出电压，并评估了在各种跌落高度和位置下的接触面积。我们证明了输出峰值电压随着接触面积的增加而增加，这与液滴的扩散和反弹有关。
Abstract Recently water droplet-based electricity generators (DEGs), which utilize triboelectricity between a droplet and a dielectric material, has a great attention. DEG generates an instantaneous high-power density despite its simple metal/dielectric/metal stack structure. In the DEG, the contact area between a droplet and a dielectric surface affects the output characteristics. We fabricated a DEG using a PTFE film as a dielectric material, measured the output voltage and evaluated the contact area in various dropping heights and positions. We demonstrated that the output peak voltage increased as the contact area increased related to spreading and rebounding of a droplet.
