Conductive hydrogels, with their unique combination of electrical conductivity and stretchability, are emerging as critical components for next-generation, flexible, wearable sensors. In this work, we aimed to develop a low-cost, easy-to-manufacture hydrogel sensor using ionic compounds the source conductivity. Hydrogels were synthesized acrylamide, poly(ethylene glycol), carboxymethyl cellulose, systematic variation LiCl, NaCl, KCl, labeled Li-CH, Na-CH, K-CH, respectively, explore effects on nanostructure mechanical properties hydrogels. Among different formulations, Na-CH demonstrated superior performance optimized elongation at break, tensile strength, toughness, highlighting importance ion selection in design. also exhibited excellent outstanding transparency, high sensitivity detecting wide range body movements, from large-scale gestures subtle physiological signals such pulse detection. With its exceptional robustness, repeatable sensing performance, shows great potential future applications flexible electronics, healthcare monitoring systems, smart display technologies.

Abstract Rechargeable aqueous zinc batteries (AZBs) utilizing water‐borne electrolytes are intrinsically safe electrochemical devices that promising in next‐generation energy storage. Such application requires adaptivity to global climate, especially at grid‐scale, thus their stability of performance varying temperatures is critical. Many essential properties AZBs, i.e., ion transfer, redox kinetics, etc., largely governed by the because relatively limited stable phase temperature water. This limitation extremely vital cold regions since charging and discharging become more difficult sub‐zero range due water freezing. Despite development various electrolyte strategies recent years, comprehensive reviews focusing on this topic remain limited. research diverse reasons underneath failure AZBs extreme provides a thorough analysis possible resolutions from an perspective. It starts with challenges faced both high low concerning electrolytes. Different addressing these discussed, providing insights into under conditions. Finally, review concludes summary outlook design structure for all‐weather integrating innovative non‐aqueous battery systems.
