Water‐Resistant Conductive Gels toward Underwater Wearable Sensing

Advanced Materials, Journal Year: 2023, Volume and Issue: 35(42)

Published: March 1, 2023

Abstract Conductive gels are developing vigorously as superior wearable sensing materials due to their intrinsic conductivity, softness, stretchability, and biocompatibility, showing a great potential in many aspects of lives. However, compared wide application on land, it is significant yet rather challenging for traditional conductive realize under water. The swelling the loss components aqueous environment, resulted from diffusion across interface, lead structural instability performance decline. Fortunately, efforts devoted improving water resistance employing them field underwater recent years, some exciting achievements obtained, which significance promoting safety efficiency activities. there no review thoroughly summarize gels. This presents brief overview representative design strategies water‐resistant diversified applications sensors. Finally, ongoing challenges further also discussed along with recommendations future.

Surface Modification of Super Arborized Silica for Flexible and Wearable Ultrafast‐Response Strain Sensors with Low Hysteresis

Advanced Science, Journal Year: 2023, Volume and Issue: 10(25)

Published: June 28, 2023

Conductive hydrogels exhibit high potential in the fields of wearable sensors, healthcare monitoring, and e-skins. However, it remains a huge challenge to integrate elasticity, low hysteresis, excellent stretch-ability physical crosslinking hydrogels. This study reports synthesis polyacrylamide (PAM)-3-(trimethoxysilyl) propyl methacrylate-grafted super arborized silica nanoparticle (TSASN)-lithium chloride (LiCl) hydrogel sensors with electrical conductivity. The introduction TSASN enhances mechanical strength reversible resilience PAM-TSASN-LiCl by chain entanglement interfacial chemical bonding, provides stress-transfer centers for external-force diffusion. These show outstanding (a tensile stress 80-120 kPa, elongation at break 900-1400%, dissipated energy 0.8-9.6 kJ m

Poly(vinyl alcohol)/polyacrylamide double‐network ionic conductive hydrogel strain sensor with high sensitivity and high elongation at break

Journal of Polymer Science, Journal Year: 2024, Volume and Issue: 62(20), P. 4599 - 4611

Published: July 19, 2024

Abstract As a soft material with biocompatibility and stimulation response, ionic conductive hydrogel‐based wearable strain sensors show great potential across wide spectrum of engineering disciplines, but their mechanical toughness is limited in practical applications. In this study, freeze‐thawing techniques were utilized to fabricate double‐network hydrogels poly(vinyl alcohol)/polyacrylamide (PVA/PAM) both covalent physical cross‐linking networks. These demonstrate excellent performance, an elongation at break 2253% tensile strength 268.2 kPa. Simultaneously, they also display high sensitivity (Gage factor, GF = 2.32 0%–200% strain), achieve rapid response time 368 ms without the addition extra fillers or ions, stable signal transmission even after multiple cycles, fast human motion detection.
