High-fidelity wireless electrophysiological monitoring is essential for ambulatory healthcare applications. Soft solid-like hydrogels have received significant attention as epidermal electrodes because of their tissue-like mechanical properties and high biocompatibility. However, it challenging to develop a hydrogel electrode that provides robust contact adhesiveness with glabrous skin hairy scalp high-fidelity, continuous signal detection. Here, paintable, fast gelation, highly adhesive, conductive engineered high-fidelity monitoring. The hydrogel, consisting gelatin, gallic acid, sodium citrate, lithium chloride, glycerol, Tris-HCl buffer solution exhibits reversible thermal phase transition capability, which endows the attributes on-skin applicability in situ gelation 15 s, thereby addressing aforementioned limitations. introduction acid enhances adhesive facilitating secure attachment or scalp. To accentuate potential applications at-home health monitoring, are demonstrated electrocardiogram recording one hour during various daily activities, well simultaneous electroencephalogram 30 min nap.

Abstract Gallium‐based liquid metals with outstanding electrical conductivity and fluidity are widely used in wearable electronics for wireless communication, human–machine interaction, smart textiles. However, their makes them easily leak from the embedded conductive circuits under repeatable stretching, mechanical damage, or exposure to acidic alkaline environments, limiting reliability practical use. Here, highly stable LM–polymer composites shown ability endure significant chemical stresses, maintaining low resistance changes ( R / 0 = 3.3 2.4) after 10 times of standard washing 24 h storage corrosive solutions. The use fluoropolymer, providing robust interfacial binding gallium oxide layer, effectively serves as a barrier layer withstand damage through synergistic effect adaptive dipole–dipole interactions among enhanced hydrophobicity. as‐prepared can be readily hot pressed onto commercial fabrics develop electronic textiles (10214 S m −1 ), high air permeability (148.6 mm s moisture (30.3 g −2 ). Taking advantage excellent stability permeability, e‐textiles demonstrated washable thermal therapy patches skin‐interfaced electrodes epidermal biopotential recording.

MXenes, a novel class of two-dimensional (2D) materials, have attracted considerable attention in various fields, especially drug delivery, wound healing, bone tissue engineering, biosensing, and cancer treatment. Thanks to their remarkable physicochemical properties, MXenes hold great promise for biomedical applications. Concurrently, hydrogels composed polymers been extensively utilized contexts. The unique properties facilitate integration into bioactive with enhanced functions thereby endowing the composites multifunctional capabilities. MXene-reinforced polymer (MRPHs) synergistically combine advantageous characteristics both hydrogels, making them highly adaptable other theranostic strategies medical In this comprehensive review, we demonstrate recent advances design synthesis MRPHs Specifically, introduce analyze methods tailoring by incorporating active components, including functional molecules, 2D metal ions, natural polymers, drugs/genes. We then discuss applications designed biosensors, therapy. hope that work provides valuable guidance inspiration readers develop advanced
