Abstract Ocean energy harvesting based on a triboelectric nanogenerator (TENG) has great application potential, while the encapsulation of devices in water poses critical issue. Herein, triboelectric–electromagnetic hybrid (TE‐HNG) consisting TENGs and electromagnetic generators (EMGs) is proposed to harvest flow energy. A magnetic coupling transmission component applied replace traditional bearing structures, which can realize fully enclosed packaging TENG achieve long‐lasting from flow. Under intense impact, reduces possibility internal gear damage due excessive torque, indicating superior stability robustness compared conventional TENG. At waterwheel rotates speed 75 rpm, TE‐HNG generate an output peak power 114.83 mW, corresponding density 37.105 W m −3 . After 5 h continuous operation, electrical attenuation less than 3%, demonstrating excellent device durability. Moreover, self‐powered temperature sensing system cathodic protection are developed illustrated.

Abstract Deploying triboelectric nanogenerator (TENG) units on and below the water surface has been a conventional method for harvesting wave energy. However, this approach restricts TENG's amplitude to that of waves, limiting actual offshore output. Here, new placing TENG above using amplifier is reported. This addresses issue insufficient in traditional energy TENGs achieves higher electrical output performance real conditions. Moreover, innovative four‐helix (FH‐TENG), designed with special pattern cutting bridging techniques, eliminates need internal wires, foundational frameworks, counterweights. Results show FH‐TENG placed over 76% increase 235% enhancement charge compared floating directly surface, maximum voltage, transferred current reach 246 V, 7.9 µC, 156.1 µA, respectively.
