With development of internet of things (IoT), many researches on triboelectric nanogenerator (TENG) are actively being carried out as energy source of sensors. In this work, a novel triboelectric nanogenerator fabricated by implanting Polytetrafluoroethylene (PTFE)-wrapping wires into porous conductive polymer (PCP-TENG) is demonstrated. Compared with conventional structure contact-separation TENG with the same material properties, PCP-TENG shows more than 60 times enhancement at amount of charge transferred (QTR). These remarkable enhancement is achieved by utilizing the wide inner surface of the porous structure as contact surface. Notably, PCP-TENG generates continous sinosoidal-like alternative current without any interval while TENG conventional contact-separation structure produces intermittent pulse-like currents. Furthermore, PCP-TENG can harvest vibrational mechanical energy from various direction and amplitude. From these advanced characteristics, PCP-TENG inserted inside tire and brightened 18 LEDs continuously by deformation of tire.
