Abstract Omnidirectional wind energy harvesting has gained increasing attention as a means of harnessing the inherently variable and multidirectional flows encountered in real-world environments. Triboelectric nanogenerators (TENGs), which leverage contact electrification electrostatic induction to convert mechanical motion into electrical power, are particularly well-suited for such applications due their ability operate effectively under low-speed intermittent conditions. In this review, we first outline fundamental triboelectric processes operating modes that underpin TENG functionality, emphasizing how low inertia high-voltage outputs make them compatible with wide range profiles. We then discuss three predominant device classifications—rotary, aeroelastic, rolling-based—highlighting distinct configurations capacities omnidirectional capture. Key examples illustrate strategically designed rotor geometries, flutter-driven films, rolling elements can maximize contact–separation events enhance generation complex airflow patterns. Finally, examine major obstacles faced by TENG-based harvesters, including durability, hybrid system design, intelligent power management. Strategies overcome these barriers involve wear-resistant materials, adaptive architectures, advanced circuitry, offering solutions feasible micro- or off-grid scenarios.
