PAPER-BASED TRIBOELECTRIC NANOGENERATORS (TENGS)

Abstract

The triboelectric effect is a type of contact charging effect in which certain materials become electrically charged after they come into contact with other materials. A nanogenerator is a device that coverts mechanical energy into electricity which demonstrates a self-power device driven by electrodes of different materials. In addition, the complex preparation process requires coating with a non-conductive layer, which limits their practical applications, but the output current of a TENG is mainly determined by the quantity of triboelectric charge carried on the friction layer. The triboelectric charge capacity and the charge driving ability of the friction layer are the key parameters for enhancing the output performance of Triboelectric Nanogenerator (TENG) As first reported in 2006, various nanogenerators (NGs) have been demonstrated using piezoelectric, triboelectric and pyroelectric effects. By using the effect of triboelectric, our goal is to make self-powered system. This research shows the combination of higher ranked triboelectric material and size optimization which ensures the high power generation. This research demonstrates a new type triboelectric nanogenerator which is fabricated using copper tape coated with polyethylene (C2H4)n as the non-conduct layer. Paper is used to separate conducting and nonconducting material. To further enhance the output of the paper-based TENG, a number of polyethylene coated surfaces which is non-conducting and conducting surfaces which is copper tape are combined together for output power. As surface area of conducting and non-conducting material is increased the output power increased. Moreover if number of papers increases, output power also increases.
