Abstract Triboelectric nanogenerators (TENGs) are effective in harvesting high‐entropy low‐frequency wave energy, yet traditional TENGs struggle to align with the meter‐scale wavelengths prevalent marine environments, significantly impairing their energy conversion efficiency. Addressing this, One Meter TENG (OM‐TENG) is introduced, a pioneering advancement design that extends shell size 1 m. This innovation features novel lantern‐shaped stacked silicon‐manganese steel sheet configuration, optimizing internal space usage, and achieving single‐cycle transfer charge of 60.82 µC friction layer area density 1.76 cm −1 . Furthermore, by integrating segmented limiter device for rational control different sliders, contact separation among numerous units realized. Comprehensive evaluations through theoretical analysis, multiphysics field numerical simulations, sensor data analytics, comparative experimental measurements have unequivocally demonstrated OM‐TENG's superior capability capturing under actual environmental conditions, alongside its remarkable anti‐capsize performance. Achieving peak outputs 584 V 444 µA, OM‐TENG can power 96 2 W LEDs drive wireless communication modules, marking significant step forward efficient utilization large‐scale TENGs.

Abstract Although high permittivity of inorganic materials (possibly two orders larger than organic polymers) is theoretically considered as ideal triboelectric materials, their leakage property and low contact potential difference with metal electrodes lead to failure obtain charge density. Besides, the internal space accumulation a result defect levels reduces output density causes dielectric loss or even breakdown under injection in charge‐excitation nanogenerator (CE‐TENG). Herein, this study proposes layers. In order prevent passing through surface caused by air excitation, an polymer coated, which has permittivity, big polarizability, none traps, large work function electrodes. After optimizing layer coated layer, CE‐TENG based on 1 mm PZT‐5H P(VDF‐TrFE‐CFE) achieves 2.83 mC m −2 , 6.5 times PZT‐5H, breaking historical record for material TENG. This clarifies selection criteria provides deeper understanding transfer mechanism materials.
