Humidity‐Resistant Wearable Triboelectric Nanogenerator Utilizing a Bound‐Water‐Rich Zwitterionic Hydrogel With Microphase‐Separated Domains

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Дек. 29, 2024

Abstract Triboelectric nanogenerators (TENGs) represent an effective approach for transforming mechanical energy into electrical power, making them suitable wearable electronic applications. Hydrogels as TENGs electrodes are common, but their use direct triboelectric layers remains insufficiently explored. Here, a novel zwitterionic monomer 3‐{1‐[6‐(hydroxymethyl)‐2‐methyl‐3,8‐dioxo‐9‐aza‐4,7‐dioxadodec‐1‐en‐12‐yl]imidazol‐3‐ium‐3‐yl}propane‐1‐sulfonate (VNIPS) is synthesized in combination with acrylic acid (AA) and sulfobetaine methacrylate (SBMA) to create double‐network hydrogel. The hydrogel developed using solvent‐exchange process that facilitated the creation of microphase‐separated domains, notablely increasing its strength (211.9 kPa, 472.3%), conductivity (0.6 mS cm −1 ), anti‐freezing capability (−18.3 °C). In addition, hydrogel's hydrophilic groups interacted water molecules, reducing charge loss humid conditions. When employed positive layer, hydrogel‐based achieved substantial density 456 µC m − 2 output power 464 mW , while maintaining steady open‐circuit voltage (V oc ) 97 V, 92% retention under 80% relative humidity. Moreover, strong adhesion biocompatibility make it applications, such motion sensing Morse code communication. This work demonstrates feasibility hydrogels materials, providing new strategy creating efficient, humidity‐resistant harvesters.

Advancing Humidity‐Resistant Triboelectric Nanogenerators Through MoS₂‐Encapsulated SiO₂ Nanoparticles for Self‐Powered Gas Sensing Applications

Advanced Energy Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 24, 2025

Abstract In this study, the humidity‐resistant triboelectric nanogenerators (TENGs) utilizing MoS₂‐encapsulated SiO₂ nanoparticles (NPs), aimed at enhancing self‐powered gas sensing applications, are reported. The core‐shell structure, featuring a thin MoS₂ layer uniformly grown on SiO₂, addresses common humidity‐induced performance degradation. growth mechanism involves decomposition and sulfidation of molybdenum species, with selectively nucleating to form stable, hydrophobic shell. This effectively shields interface from water molecule penetration, thus stabilizing charge density significantly reducing decay, even under high humidity conditions. TENGs constructed these NPs exhibit exceptional durability, retaining more than 70% output over 25 h 99% relative (RH). Furthermore, fabricated TENG reliably powers sensor array, enabling accurate detection in extreme humidity. work demonstrates potential as robust, energy solutions for environmental monitoring wearable devices challenging
