A layered structure of triboelectric nanogenerator (TENG) has been fabricated in the contact separation mode with plain paper, highly dielectric (PTFE) polytetrafluoroethylene and conductive aluminium layers, respectively. The output responses were recorded in form of electrical voltage by the triggering of mechanical interactions over the TENGs surface. A size dependent analysis has been studied, followed by the function of current density and generated power. Thermal behaviour on the TENG surface revealed an inverse output voltage response.
