Liquid-Solid Triboelectric Nanogenerators

The triboelectric nanogenerator (TENG) has emerged as a notable innovation in energy research, converting mechanical energy into electrical energy through the triboelectric effect and electrostatic induction. Of its many variations, the liquidsolid mode TENG has gained significant attention due to its inherent wear resistance, mechanical durability, and consistent operation. This research provides a focused exploration into the interactions between solids and liquids within the domain of TENGs. Beginning with an overview of TENGs—from the general background to their various operational modes, followed by a comprehensive literature review of solid-liquid TENGs.
