Abstract The electrical double layer (EDL) between solids and liquids serves as the primary interface for ionic‐electronic coupling is pivotal in nanoscale phenomena, governing electric field effects, ion transport, surface interactions, etc. Dynamically regulating EDL through mechanical or electrostatic methods can influence charge carrier behavior, thereby impacting energy scavenging storage processes. This regulation enabled efficient by ionic migration optimizing concentration at interface, presenting a novel avenue to achieve information flow. Here, various devices dynamically are systematically reviewed. They classified into three groups distribution movement of carriers throughout entire EDL, diffuse layer, Debye length range. review provided comprehensive overview operating principles, influencing factors, output characteristics, typical applications, along with discussion on future challenges. holistic examination offers researchers valuable insights evaluating their applicability scenarios.

The textile triboelectric nanogenerator (TENG) has emerged as a robust energy harvesting technology for portable power systems and wearable electronics applications. However, the susceptibility of material to ambient humidity temperature profoundly influences performance TENG, creating bottlenecks in development textile-based TENG devices. This study investigates impact (20–70 °C) (20–90%) on vertical sliding contact separation modes. results show significant both parameters, reducing voltage current by 89 84%, respectively, relative increases. moisture present atmosphere shown negative effect charge transfer, demonstrating gradual reduction transferred with humidity. Similar were observed when increasing from 20 70 °C; reduced 79 64%, respectively. When examining humidity, it becomes evident that exerts more pronounced effect, primarily attributable interaction fibers.

Abstract Triboelectric nanogenerators (TENGs) represent a promising next‐generation renewable energy technology. TENGs have become increasingly popular for harvesting vibration in the environment due to their advantages of lightweight, broad range material choices, low cost, and no pollution. However, issues such as input force irregularity, working bandwidth, efficiency calculation, dynamic modeling hinder use industrial or practical applications. In this paper, process dynamical system TENG is reviewed from perspective flow. addition, paper reviews main contributions made recent years achieve optimized output based on springs, magnetic forces, pendulums, introduces different ways increase bandwidth TENGs. Finally, problems are discussed. This review may serve reference methods convert irregular mechanical sources into performance toward commercialization

Bimetallic metal−organic framework (MOF)‐derived multidimensional composites have garnered tremendous attention in electromagnetic wave absorption owing to their remarkable attenuation capacity. And the diversified application scenarios require microwaves materials (MAMs) with robust environmentally adaptive, but efficiently integrating multifunctionality within single MAMs is extremely challenging. Herein, a multifunctional CoC@FeNiG‐F nanocomposite fabricated by synergistic strategy of situ growth, C–F···π interaction and microwave irradiation. The exhibit strong reflection loss −75.18 dB 3.95 GHz effective bandwidth benefited from magnetic–dielectric attenuation, impedance matching, multiple‐reflection loss. Remarkably, it first time obtain efficient accompanied excellent mechanical (80.3 MPa), superamphiphobicity (153° 151°), anticorrosion (45 d), flame retardancy (V‐0 rating), which illustrate that combination CoC@FeNiG 3D‐skeleton long‐chain perfluorinated epoxy remarkably improve adaptive. In particular, are assembled into liquid–solid triboelectric nanogenerator, output performance (19.7 V, 1.68 μA) durability (10 000s) obviously improved benefiting trap effect carbonized MOF. Therefore, this work provides an guideline for designing advanced adaptive sustainable energy harvesting extreme environment application.
