Integrated Triboelectric Nanogenerator for Energy Harvesting: Efficient Absorption of Wind in 6–16 m s−1 Velocity Range and Wave Energy

The ocean harbors an abundance of resources, encompassing not only wave energy but also considerable wind energy. Triboelectric nanogenerator (TENG), as a technology for harvesting low‐frequency, high‐entropy mechanical energy, has shown distinct advantages in the collection and application of marine and wind energy. This study introduces a triboelectric Wind and wave energy harvester (TWWEH), an energy collector based on TENG, which can be used to harness wind and wave energy. The TWWEHs comprise a wind‐driven TENG (W‐TENG) for wind energy collection and a ring‐shaped TENG (R‐TENG) for wave energy collection. The proposed vertically integrated TENG architecture enhances spatial utilization rate. Under oscillatory conditions of 0.8 Hz and ±30°, the R‐TENG generates a peak power of 0.20 mW. While at a wind speed of 10 m s −1 , a peak power of the W‐TENG can reach 0.11 mW. This research provides a promising solution to harvest wave and wind energy from the ocean, offering significant potential applications in establishing self‐powered oceanic assessment and meteorological systems.
