The effect of dielectric constant and work function on triboelectric nanogenerators: Analytical and numerical study

Abstract

In this study, an analytical model of triboelectric charge density and transferred charge density for simple contact-mode triboelectric nanogenerators (TENG) is constructed. The model comprises the characteristics of triboelectric materials, such as dielectric constants and work function, and structural parameters such as the thickness of the dielectric material and the separation distance between the metal and dielectric. The model presented in this paper is the analytical interpretation of the metal to dielectric contact-mode TENG and is intended to serve as a guideline for the design of TENGs in various applications.
