Abstract Traditional triboelectric nanogenerators (TENGs) face significant challenges related to low charge density and high internal impedance. Many methods have been proposed enhance the surface of TENGs, yet they do not simultaneously achieve resistance. Here, a switch‐shuttling nanogenerator (SS‐TENG) is proposed. By periodically interrupting circuit during intrinsic capacitance variation TENG shuttle process, SS‐TENG alters potential difference while maintaining constant in capacitor, thereby enhancing energy storage improving overall output performance. The rapid activation switch significantly reduces Compared traditional transfer amount increases by 1.9 times, short‐circuit current rises 9.6 with resistance reduced factor 20. Furthermore, prototype novel cylindrical‐hexagram bluff body (CHB) vortex‐induced vibration harvester based on designed tested, demonstrating its ability reliably harvest from underwater tidal flows wave energy. Additionally, self‐powered marine pollution detection strategy has developed using SS‐TENG. This work provides valuable insights for performance TENGs actively promotes their commercialization.

Abstract Triboelectric nanogenerators (TENGs) show potential for powering distributed sensors in the smart grids. However, most studies on TENG's applications energy harvesting from transmission lines primarily focus vibration and wind energy, neglecting abundant electric‐field systems. This study proposes a triboelectric‐electrostatic hybrid harvester (TEHEH) that integrates triboelectric nanogenerator with an (EFEH) to simultaneously capture surroundings of lines. The TENG EFEH can generate open‐circuit voltages 1280 2800 V, respectively, output powers 14.3 28.9 mW. Hybrid achieves average power 6.1 times 2.4 EFEH, demonstrating its superiority. dual‐channel management circuit, utilizing gas discharge tube LTC‐3588, enables effectively wireless sensor node, practicality complex environments work offers robust technical support development self‐powered monitoring devices high‐voltage
