Abstract

The triboelectric nanogenerator (TENG) has proved to be an important innovation in the field of self-powered sensors. It utilizes triboelectrification and electrostatic induction in order to generate power. Multiple types of TENGs exist, but one type that uses electrostatic breakdown to generate power is the sliding direct current TENG (DC-TENG) that consists of a friction electrode (FE) and a charge collecting electrode (CCE). This paper discusses the factors affecting the coefficient of friction (COF) between a DC-TENG and the triboelectric layer (TL). The tested DC-TENG had a trailing CCE that was allowed to float on the surface of the lubricating oil.
 
It was found that lubrication via motor oil showed the lowest values of (COF) in most cases. But for high sliding velocitys and low normal load conditions, the dry sliding condition gave the lowest values of COF. It was revealed that COF also increased with normal force in all cases except when lubricated by motor oil. The relationship between the COF and the sliding velocity of the DC-TENG was found to follow the Stribeck diagram. COF was also found to increase with load resistance due to charge accumulation on the FE.
