Conductive hydrogels, widely recognized as flexible sensor materials for health monitoring, pose a research challenge in selecting suitable frameworks and designing multifunctional composites that balance conductivity, transparency, self-healing, mechanical properties. In this work, simple efficient plant-template method (corn husk) is used to generate textured hydrogel (PPA) with PEI PVA the transparent framework, without additional cross-linking agents. The resulting exhibits high conductivity (8.56 S/m), excellent transparency (94% @ 550 nm nontextured variant), remarkable stretchability (627.1%). Additionally, PPA self-healing capabilities, achieving maximum efficiency of 94.68%. To enhance AgNWs are applied surface using rod coating method, forming PPA@RCA 12.39 S/m. This improvement attributed interactions between silver-based nanomaterials (AgNWs, AgNPs), Li+, PEI/PVA framework PPA@RCA. wearable strain based on features gauge factor 3.35 instantaneous response characteristics (response time 195 ms), exhibiting exceptional sensitivity repeatability across diverse ranges external stimuli. Therefore, ultrahigh-conductive hydrogel, produced through strategy, demonstrates significant potential applications tablet capacitive pens, writing devices, smart wearables, monitoring.

Abstract Liquid metal nanoparticles (LMNPs) are being considered as promising candidates for printable electronics owing to their high conductivity and fluidity, well improved wettability comparable that of bulk LMs. However, the surface tension weak adhesion LMNPs pose formidable challenges facile patterning on various substrates diverse applications. Herein, a new LMNP‐polymer composite is reported multifunctional electronics, which achieved by introducing α ‐lipoic acid (LA)/choline chloride (ChCl) polymerizable deep eutectic solvents (PDESs) ideal polymer carriers. Simply with ring‐opening polymerization (ROP) LA, highly conductive LMNP‐PDES composites can be patterned using printing methods. Benefiting from hydrogen bondings within PDES, printed traces feature enhance consistent performances under different deformations. More importantly, they easily dissolved in ethanol via thermal treatment reprinted further use, showing excellent recyclable capability. Demonstrations stretchable sensor, conformal electrode, smart actuator validate versatility reliability this composite, ensuring its broad prospects electronics.
