Negatively charged nanogenerator (TENG) has some critical limitation for accomplishing electric generator role such as low current density, power continuity, etc. To supplement weak point of TENG, here, we introduce parallel-contacted negatively charged nanogenerator (PCTENG) with additional metal middle layer acting as ground layer. Aluminum is used as electrode and middle layer, Polytetrafluoroethylene (PTFE) is used as active layer and etched by reactive ion etching (RIE). The working mechanism of PCTENG is based on triboelectrification of PTFE and Al, aluminum middle layer enhances performance of PCTENG. Using this PCTENG, we also demonstrate portable self - generator for application. Performances of basic structure PCTENG are 150 µA/cm2. (Active layer area is 4 4 cm2)
