Abstract
Triboelectric nanogenerators (TENGs) are a promising energy-harvesting technique that utilizes contact electrification and electrostatic induction to convert mechanical energy into electrical energy. Contact electrification can occur between any two surfaces that experience periodic physical contact and separation, regardless of the material type. Various materials have been investigated for triboelectrification in TENGs for different applications. Although polymers are used in TENGs, various transition metal oxides (TMOs), including binary, ternary, and doped binary/ternary oxides, have also been widely studied as filler materials to improve TENG performance. Introducing TMOs into the polymer matrix enhances the performance by increasing surface charge density and enabling more efficient charge separation and transfer across the triboelectric interface. In this review, we summarize the effect of binary oxides, ternary oxides, and the doped binary/ternary oxides on the performance of TENGs. Furthermore, the review discusses the challenges and future advancements in optimizing the power generation of TENGs.
