Triboelectric nanogenerators with nature-replicated interface structures are presented. Effective contact areas of the triboelectric surfaces are largely enhanced because of the densely packed nano-in-micro hierarchical structures in nature. The enlarged contact area causes stronger triboelectric charge density, which results in output power increment. The interface engineering also allows the improved humidity resistance, which is an important parameter for the stable energy harvesting.
具有自然复制界面结构的摩擦纳米发电机被提出。由于自然界中存在着密集排列的纳米级-微米级分级结构，摩擦表面的有效接触面积得到了极大的提高。增大的接触面积导致更强的摩擦电荷密度，从而产生更高的输出功率。界面工程还提高了耐湿性，这是稳定能量收集的一个重要参数。
