6G communication mainly occurs in the THz band (0.1–10 THz), which can achieve excellent performance. Self-powered modulators are essential for achieving better conduction, modulation, and manipulation of waves. Herein, a self-powered terahertz modulator, is based on metamaterials, liquid crystals (LCs), rotary triboelectric nanogenerators (R-TENGs), proposed to realize driving different array elements. The corresponding designs an integrated design preparation method dynamic spectrum-reconfigurable crystal metamaterials. In addition, type cross-structure metamaterial box, phase modulation 1 GHz achieved at frequencies 0.117 0.161 with depths 13 11%, respectively. Because R-TENG multifan blade circular electrodes generate 18 peaks electric output every rotation, it successfully provide sufficient frequency alternating-current energy drive modulator function. Our findings lay solid theoretical foundation further building systems promote development system LC-driving devices domain.

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.
