中文摘要：

我们基于一个 graphene 网络(GN ) 报导一个电压发电机。响应在 GN 脱衣上的离子的答案的微滴的运动，几百毫伏特的电压在周围的条件下面被观察。在电压产生过程， GN 的唯一的结构在改进电子转移的率起一个重要作用。给他们的优秀机械性质， GN 可以为在象被暴露下雨的雨衣，伞，窗口，和另外的表面那样的各种各样的地方收获震动的精力发现应用。

英文摘要：

We report a voltage generator based on a graphene network （GN）. In response to the movement of a droplet of ionic solution over a GN strip, a voltage of several hundred millivolts is observed under ambient conditions. In the voltage-generation process, the unique structure of GN plays an important role in improving the rate of electron transfer. Given their excellent mechanical properties, GNs may find applications for harvesting vibrational energy in various places such as raincoats, umbrellas, windows, and other surfaces that are exposed to rain.
