Nacre-Mimetic Structure Multifunctional Ion-Conductive Hydrogel Strain Sensors with Ultrastretchability, High Sensitivity, and Excellent Adhesive Properties

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: unknown

Published: April 12, 2024

Recently, conductive hydrogels have emerged as promising materials for smart, wearable devices. However, limited mechanical properties and low sensitivity greatly restrict their lifespan. Based on the design of biomimetic-layered structure, with nacre-mimetic structure were prepared by using layered acrylic bentonite (AABT) phytic acid (PA) multifunctional "brick" "mortar" units. Among them, unique rigid cyclic multihydroxyl "organic mortar" PA preserves both ultrastretchability (4050.02%) high stress (563.20 kPa) hydrogel, which far exceeds most reported articles. Because synergistic effect AABT PA, hydrogel exhibits an excellent adhesive strength (87.74 kPa). The role in is proposed first time, a general strategy improving demonstrated. Furthermore, provides ion channels ionizes abundant H+, conferring gauge factor (GF = 14.95) antimicrobial to hydrogel. Also, inspired fruit batteries, simple self-powered flexible sensors developed. Consequently, this study knowledge functional filler modified ionic shows great application potential field intelligent

Stimulus-responsive polysaccharide-based hydrogels: From design to biomedical applications

Precision medicine and engineering., Journal Year: 2024, Volume and Issue: 1(1), P. 100001 - 100001

Published: July 28, 2024

Stimulus-responsive hydrogels can undergo controllable shape deformation and exhibit sol-gel transition behavior under stimulus signals such as pH, reactive oxygen species (ROS), heat, light. Polysaccharides have become ideal candidates for constructing stimulus-responsive due to their biocompatibility biodegradability. The diversity of molecular weights functional groups polysaccharides allows them self-assemble or cooperate with other materials obtain through physical chemical crosslinking. Bioactive ingredients nanomaterials be conveniently encapsulated in the hydrogel matrix meet various requirements. polysaccharide-based are widely used biomedical field, especially fields drug delivery, tissue engineering, biosensors, imaging. In this review, design strategies recent research advances stimuli-responsive summarized. Future challenges also presented, review will guide study polysaccharide hydrogels.
