Advanced Materials, Год журнала: 2024, Номер unknown

Опубликована: Сен. 14, 2024

Abstract Ionogels are an emerging class of soft materials for flexible electronics, with high ionic conductivity, low volatility, and mechanical stretchability. Recyclable ionogels recently developed to address the sustainability crisis current through introduction non‐covalent bonds. However, this strategy sacrifices robustness chemical stability, severely diminishing potential practical application. Here, covalent adaptable networks (CANs) incorporated into ionogels, where dynamic crosslinks endow strength (11.3 MPa tensile strength), stretchability (2396% elongation at break), elasticity (energy loss coefficient 0.055 100% strain), durability (5000 cycles 150% strain). The reversible nature CANs allows ionogel be closed‐loop recyclable up ten times. Additionally, is toughened by physical between conducting ions polymer networks, breaking common dilemma in enhancing properties electrical conductivity. demonstrates robust strain sensing performance under harsh treatments applied reconfigurable multimodal based on its recyclability. This study provides insights improving toward functionally reliable environmentally sustainable bioelectronics.

Damping Supramolecular Elastomer for Steady Hypothermic Sensing

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 24, 2025

Abstract Flexible temperature sensors often use gels to achieve skin‐inspired softness, but the water evaporation and freezing of hydrogel leakage ionogel, cause unstable signal transmission inaccurate measurement at sub‐zero temperatures. Here steady hypothermic sensing is achieved by designing a supramolecular elastomer containing two types segments: liquid‐free iontronic segment transmit electrical charges prevent ion leakage, neutral with pendant chains damp vibration for stable transmission. The exhibits excellent tensile properties, adhesiveness, self‐healing, ionic conductivity A wireless system fabricated based on supermolecule elastomer, realizing accurate, steady, sensitive real‐time detection. Especially, sensor coefficient resistance (TCR) 8.87% °C −1 from −20 −15 °C, three five times higher than that most flexible sensors. There no significant difference in detected this an infrared thermal imaging camera. Such represents step toward highly accurate cold chain transportation beyond.

Multifunctional Hydrogel Electronics for Synergistic Therapy and Visual Monitoring in Wound Healing

Advanced Healthcare Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 9, 2025

To overcome the limitations of precise monitoring and inefficient wound exudate management in healing, an advanced multifunctional hydrogel electronics (MHE) platform based on MXene@MOF/Fe3O4@C photonic crystal is developed. This combines optical/electrical sensing, synergistic therapy, real-time visual into a single, efficient system, offering comprehensive solution for healing. Under photothermal stimulation, releases metal ions that generate hydroxyl radicals, effectively eliminating antibiotic-resistant bacteria. Beyond its antibacterial efficacy, this system offers unprecedented through temperature-responsive visualization, while structural color changes upon absorption provide clear indication dressing replacement. By integrating these functionalities, MHE allows control therapeutic process, significantly improving healing treatment monitoring. The platform's sensing capabilities further broaden potential applications across other biomedical fields. breakthrough technology provides clinicians with powerful tool to optimize outcomes, marking major advancement care applications.
