Anti‐Self‐Excited Oscillation Triboelectric Nanogenerators for Energy Harvesting of Aeolian Vibration in Transmission Line

Ensuring the reliability and stability of long‐distance power transmission requires monitoring the transmission lines' and grid environment's health. For this purpose, this study proposes a triboelectric nanogenerator (TENG) with anti‐self‐excited vibration. In case of aeolian vibration in the transmission line, the anti‐self‐excited oscillation triboelectric nanogenerator (AO‐TENG) generates electricity via cohesive work between the spring and the additional weight block that drives the TENG. As a result, this prevents excessive surge voltage from damaging the back‐end circuit, and the capacitor contributes significantly to voltage drop. This solution solves the issue that arises due to the TENG's high output voltage, making it difficult to power commercial sensors. This study presents a new design solution to facilitate smart grids that guarantee stable operation of distributed sensor nodes in the grids.
