Bionic electronic skin, with its integrated biological functions, is capable of sensing and responding to external stimuli, potentially surpassing the ideal flexibility natural skin in certain aspects. Most current preparation strategies employ "bottom-up" approach, using various monomers or polymer materials construct artificial networks through physical chemical cross-linking, leading issues complexity limited performance. In this work, we adopted a "top-down" strategy, which collagen fiber network aluminum-tanned sheepskin was utilized as scaffold load itaconic acid (IA) hydroxyethyl acrylate (HEA). The subsequent situ polymerization IA HEA led formation poly(itaconic acid-co-hydroxyethyl acrylate) (P(IA-HEA)) filling among skeleton, results successful fabrication high-strength bionic based on (LIHEZ). advantage approach that it can retain structure properties give resulting LIHEZ multiple functions (e.g., electrical conductivity, adhesion, bacteriostasis, biocompatibility, environmental stability), thereby replicating even performance animal skin. demonstrated sensitive stimulus responsiveness durability could serve multimodal sensors (strain, temperature, humidity, bioelectricity) efficiently monitor human movements, physiological signals, changes temperature humidity. This diversified data collection provides reliable assurance for monitoring health. present construction method substrate not only breaks conventional single applications but also new insights selection flexible device substrates, promising be next-generation material constructing intelligent

Stretchable Organohydrogel with Adhesion, Self-Healing, and Environment-Tolerance for Wearable Strain Sensors

ACS Applied Materials & Interfaces, Journal Year: 2023, Volume and Issue: 15(24), P. 28993 - 29003

Published: June 7, 2023

Stretchable hydrogels as landmark soft materials have been efficiently utilized in the field of wearable sensing devices. However, these mostly cannot integrate transparency, stretchability, adhesiveness, self-healing, and environmental adaptability into one system. Herein, a fully physically cross-linked poly(hydroxyethyl acrylamide)-gelatin dual-network organohydrogel is prepared phytic acid-glycerol binary solvent via rapid ultraviolet light initiation. The introduction gelatin second network endows with desirable mechanical performance (high stretchability up to 1240%). presence acid not only synergizes glycerol impart environment-tolerance (from -20 60 °C) but also increases conductivity. Moreover, demonstrates durable adhesive toward diverse substrates, high self-healing efficiency through heat treatment, favorable optical transparency (transmittance 90%). Furthermore, achieves sensitivity (gauge factor 2.18 at 100% strain) response time (80 ms) could detect both tiny (a low detection limit 0.25% large deformations. Therefore, assembled organohydrogel-based sensors are capable monitoring human joint motions, facial expression, voice signals. This work proposes facile route for multifunctional transducers promises practical application flexible electronics complex scenarios.
