Simulation model of a non‐contact triboelectric nanogenerator based on electrostatic induction

Based on the coupling effects of contact electrification and electrostatic induction, a triboelectric nanogenerator (TENG) can convert mechanical energy into electric power, which is at cutting edge alternative technology. Although considerable number TENGs with different configurations have been designed, some them however, only depend induction effect not received enough attention. Here, non-contact TENG model consists copper rings charged dielectric sphere presented, aimed exploring working process caused by induction. Two classical models, including vertical horizontal double models are also proposed. Relevant advanced accurate established through finite element method. We anticipate that constructed theoretical analysis helpful for design complicated geometric construction, expand their applications in various fields.
