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

Abstract One of the key challenges in developing gel‐based electronics is to achieve a robust sensing performance, by overcoming intrinsic weaknesses such as unwanted swelling induced deformation, signal distortion caused dehydration, and large hysteresis signal. In this work, structural gel composite (SGC) approach presented encapsulating conductive hydrogel/MXene with lipid (Lipogel) layer through an situ polymerization. The hydrophobic Lipogel coating fulfills SGC unique anti‐swelling property at aqueous environment excellent dehydration feature open‐air, thus leading long‐term ultra‐stability (over 90 days) durability 2000 testing cycles) for underwater mechanosensing applications. As result, based mechanoreceptor demonstrates high stable sensitivity (GF 14.5). Moreover, several conceptual sensors are developed unveil their profound potential monitoring human motions, waterproof anti‐counterfeiting application, tactile trajectory tracking.

Abstract Hydrogel‐based electronics have found widespread applications in soft sensing and health monitoring because of their remarkable biocompatibility mechanical features similar to human skin. However, they are subjected potential challenges like structural failure, functional degradation, device delamination practical applications, especially facing extreme environmental conditions (e.g., abnormal temperature humidity). To address these, ionically conductive organohydrogel‐based developed, which can perform at subzero elevated temperatures (thermal compatibility) as well dehydrated hydrated environments (hydration for extended applications. More specifically, gelatin/poly(acrylic acid– N ‐hydrosuccinimide ester) (PAA–NHS ester)‐based ionic‐conductive organohydrogel is synthesized. By introducing a glycerol–water binary solvent system, the gel maintain softness wide range (from −80 60 °C). Besides, excellent conductivity achieved under various by soaking into lithium chloride anhydrous (LiCl) solution. Strong adhesion with skin, even water, be realized covalent bonds between NHS ester from amino groups The performances LiCl‐loaded PAA‐based (L‐PAA‐OH)‐based further demonstrated freezing high underwater conditions, unveiling promising prospects wearable conditions.
