A Freeze‐Resistant, Highly Stretchable and Biocompatible Organohydrogel for Non‐Delayed Wearable Sensing at Ultralow‐Temperatures

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(16)

Published: Jan. 2, 2024

Abstract Wearable electronics based on conductive hydrogels (CHs) easily suffer from prolonged response times, reduced wearing comfort, shortened service lives, and impaired signal accuracy in cold environments, because conventional CHs tend to freeze at subzero temperatures lose their flexibility, adhesion, transparency, conductivity, which will limit applications extreme environments. Inspired by the way psychrotolerant creatures superabsorbent materials interfere with hydrogen bonding networks of water, a freeze‐resistant organohydrogel (COH) is facilely fabricated. The synergy effect between charged polar terminal groups binary solvent system water–ethylene glycol weakens water molecules endows COH remarkable freezing tolerance (−78 °C). Additionally, obtained ultra‐stretchable (≈6185%), tough (9.2 MJ m −3 ), highly transparent (≈99%), self‐adhesive (10.2–27.8 kPa), biocompatible. This versatile assembled into strain sensor well‐designed bracelet electrocardiogram sensor. Benefiting exceptional low‐temperature prepared COH, these devices exhibit fast delay‐free signals even −40 °C. Overall, this work proposes strategy develop multifunctional COHs for supporting human health
