Abstract
In the previous Chaps. 2–5, we have extensively discussed the fundamental working principle, theoretical analysis, and device configurations of the fundamental working modes of triboelectric nanogenerators (TENGs) . In this chapter, we will try to discuss the modeling and fundamental output characteristics of TENGs. The TENG has intrinsic capacitive behavior since it is based on a conjugation of contact electrification and electrostatic induction. After examining the theoretical basis and fundamental physics of the TENG, its governing equation is its V-Q-x relationship and its first-order equivalent model is a series of a voltage source and a capacitor. We have developed theoretical calculation method for TENGs and studied their load characteristics. When TENGs are connected with resistive loads, a three-working-region behavior is shown due to the impedance match mechanism. An optimum resistance is observed to maximize the TENG output on the load. When TENGs are utilized to charge a capacitor through bridge rectifier, it has a saturation charging behavior and is equivalent to the first-order resistor-capacitor charging. An optimum capacitive load is also observed to maximize the energy storage. Our systematic analysis provides guidance to the design of nanogenerator based systems for maximum utilization of output power.
