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.

Abstract With the rapid development of intelligent transportation systems (ITS), real‐time monitoring vehicle motion state (sharp deceleration, sharp turn, etc.) is very important to improve road traffic safety and efficiency. However, existing methods rely heavily on high‐cost equipment additional power supply requirements. Therefore, this paper proposed a gyroscope‐inspired triboelectric three‐axis acceleration sensor (GTTAS) for monitoring. The GTTAS utilizes structural characteristics gyroscope efficiently integrate horizontal sensing unit (HASU) vertical (VASU) realize three orthogonal axis accelerations. Meanwhile, adopting soft contact non‐contact electrode arrangement, can work effectively in low range. experimental results show that shows good fitting relationship range 1–15 m −1 s 2 3.5–30 . In addition, has ability pitch roll angles. Finally, system constructed, strategy early warning presented. This provides an effective solution preventing accidents demonstrates potential wide application systems.

Abstract With the development of smart grids, efficient condition monitoring high voltage transmission system has become crucial, necessitating reliable power supplies for distributed sensors. Traditional energy harvesters often focus on either internal or external sources, limiting overall efficiency. This study introduces a triboelectric‐electromagnetic‐electric field hybrid harvester (TEE‐HEH) that synergistically integrates triboelectric nanogenerators (TENGs), electromagnetic generators (EMGs), and electric (EEHs) to simultaneously capture wind energy. Electric is harvested via displacement currents between lines ground, while TENGs EMGs efficiently low‐ high‐speed energy, respectively, enabling broadband harvesting (2.3–10 m s −1 ). The synergistic combination TENG, EMG, EEH within TEE‐HEH leads significantly enhanced efficiency from multiple sources. At speed 5 , line 25 kV, distance 1.5 m, achieved peak outputs 18.5 mW (TENG), 262 (EMG), 1.85 (EEH), demonstrating collection An environmental been powered, TEE‐HEH's practicality dual‐source in grid applications.
