“…Water harbors significant energy reserves in diverse forms, serving as a sustainable energy reservoir. − Hydropower, for instance, generates approximately 16% of the world’s total annual electricity, playing an indispensable role in communication, industrial production, transportation, and other sectors. − However, traditional hydropower relies on rivers and waves to provide potential energy, is heavily dependent on topography and water resources, and is expensive to build, − making it unsuitable for arid and remote areas without surface water. Fog, an alternate manifestation of water, pervades the atmosphere extensively yet remains an underutilized natural asset. , Harnessing energy from fogwater presents substantial advantages.…”

Utilizing the ubiquitous fog in nature to create decentralized energy-harvesting devices, free from geographical and hydrological constraints, presents an opportunity to foster sustainable power generation. Extracting electrical energy from fog relies heavily on fog-digesting performance. Improving the efficiency of fogwater utilization remains a formidable challenge for existing fogwater energy-harvesting technologies. Inspired by the waterharvesting behavior of Tillandsia leaves, a smart lanceolate surface is developed to harvest triboelectric energy by rapidly digesting fog. Such a surface exhibits capabilities in fog management, encompassing precise fog capture, transportation, and critical droplet separation. Specifically, fog droplets condense at hydrophilic sites of acylated cellulose ester, subsequently migrating toward the rear under Laplace pressure, thereby producing energy as they traverse through the tail end. Such architecture yields a brief voltage restoration period (with an average of 9.36 s), can rush the capacitor to 11.59 V within 20 s, and achieves a water-digestion rate of up to 71.05 kg/m 2 h. This biomimetic approach enhances the water-digestion efficacy of the atmospheric water energy apparatus and offers perspectives on mitigating deficiencies in power resources.

Self‐healing materials that integrate excellent mechanical properties and high healing efficiency meet the requirements of flexible electronic sensors for mechanical flexibility and reliability. In the field of wearable devices, they are of great significance for improving the stability of the equipment and reducing the frequency of replacement. However, the high strength of materials often limits their self‐healing ability. When damage occurs, it will hinder the microstructural adjustment and fluidity of the material at the damaged site, thus negatively affecting the activation and execution of the self‐healing mechanism. In this study, a strength‐toughness and room‐temperature self‐healing triboelectric material is prepared by the dynamic nanoconfinement effect and the quenching effect of ethanol (referred to as the DNCQ strategy). The quenching effect of ethanol improves the aggregation of nanocluster phase, and the constructed nanoconfined network skillfully balances the contradiction between mechanical properties and self‐healing ability. The obtained triboelectric material has high tensile strength (27.1 MPa), toughness (97.9 MJ m−3), and excellent healing efficiency (88.6%). The self‐powered pressure distribution sensing array based on triboelectric materials can accurately reflect the pressure distribution of the object, which has potential application prospects in the field of wearable devices.

The seamless integration of advanced triboelectric nanogenerators with fiber material has propelled the rapid advancement of intelligent wearable electronics. The overheating and mechanical abrasion associated with prolonged operation poses a significant challenge for conventional fiber‐based triboelectric materials. Aramid fibers, characterized by high thermal stability, ultra‐high mechanical strength, and excellent insulating properties, can effectively compensate for the limitations of triboelectric materials. However, the intrinsic advantages of aramid fiber triboelectric materials and their general structural design strategies have not yet to be comprehensively elucidated. In this review, the synthesis methods and development history of aramid fiber triboelectric materials in recent years are summarized. Importantly, the unique advantages and development potential of aramid fibers as triboelectric materials are systematically discussed, particularly regarding high‐temperature resistance, high strength, and electrical insulation. Furthermore, the latest advancements in the structural design and performance modulation of aramid fiber triboelectric materials are presented. The aramid fiber‐based self‐powered wearable electronics in high‐temperature warning, impact monitoring, and human energy harvesting are summarized. Finally, the challenges and opportunities facing the future development of aramid fiber‐based triboelectric nanogenerators are discussed.
