Abstract Efficient conversion of mechanical energy into DC remains a challenge with existing methods, including Triboelectric Nanogenerators (TENGs). In ionic tribomaterials, ion displacement and polarization enable dynamic control over charge magnitude direction, like tribovoltaic nanogenerators (TVNGs), but unlike dielectric TENGs, where conductivity triboelectric are often in tradeoff. Although tribomaterials gaining interest, their potential for generating output has not been explored. We demonstrate that modifying conventional materials components, such as PVC plasticizers, can convert AC to DC. This mechanism, driven by contact electrification electrode (EP), enables stable generation across multiple modes—an issue commonly limiting methods. this study, we develop an ionic-based TENG produces continuous output, showcasing superior characteristics PVC-based bridging the limitations both TVNGs TENGs through dynamics, advancing sustainable harvesting technologies.

Abstract With the continuous development of wearable electronics, wireless sensor networks and other micro-electronic devices, there is an increasingly urgent need for miniature, flexible efficient nanopower generation technology. Triboelectric nanogenerator (TENG) technology can convert small mechanical energy into electricity, which expected to address this problem. As core component TENG, choice electrode materials significantly affects its performance. Traditional metal often suffer from problems such as durability, limits further application TENG. Graphene, a novel material, shows excellent prospects in TENG owing unique structure electrical properties. This review systematically summarizes recent research progress TENGs based on graphene electrodes. Various precision processing methods electrodes are introduced, applications electrode-based various scenarios well enhancement performance discussed. In addition, future also prospectively discussed, aiming promote advancement TENGs.

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.
