Bio‐Inspired Highly Stretchable and Ultrafast Autonomous Self‐Healing Supramolecular Hydrogel for Multifunctional Durable Self‐Powered Wearable Devices

Small, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 23, 2025

Abstract As skin bioelectronics advances, hydrogel wearable devices have broadened perspectives in environment sensing and health monitoring. However, their application is severely hampered by poor mechanical self‐healing properties, environmental sensitivity, limited sensory functions. Herein, inspired the hierarchical structure unique cross‐linking mechanism of hagfish slime, a self‐powered supramolecular hereby reported, featuring high stretchability (>2800% strain), ultrafast autonomous capabilities (electrical healing time: 0.3 s), self‐adhesiveness (adhesion strength: 6.92 kPa), injectability, ease shaping, antimicrobial biocompatibility. It observed that embedding with highly hygroscopic salt LiCl hydrogel, not only showed excellent electrical conductivity but also presented favorable anti‐freezing water retention properties extremely cold environments natural settings. Given these attributes, served as multifunctional durable device sensitivity (gauge factor: 3.68), fast response time (160 ms), low detection limit, frequency sensitivity. Moreover, applicability this further demonstrated long‐term sensing, remote medical communication, underwater communication. Overall, findings pave way for sustainable development hydrogel‐based are self‐powered, durable, offer performance, adaptability, multi‐sensory capabilities.
