lnteligent response hydrogels have significant application prospeets due to their ability to sense andrespond to environmental changes. However, many smart hydrogels are limited by weak mechanical propertiesand poor electrical conductivity.In this experiment, a temperature-responsive AgP ( NIPAM-C0-AAm) -NaCnydrogel was synthesized using N-isopropylacrylamide (NIPAM) and acrylamide ( AAm) as monomers, with nano-silver sheets as conductive fillers.'This hydrogel demonstrates an ultimate strain exceeding 700% , higlelectrical conductivity, and tunable low adhesion properties, effectively mitigating noise caused by motionartifacts during normal physiological activities,By adjusting the ratio of N-isopropylaerylamide ( NIPAM)andacrylamide ( AAM) , the hydrogel’s lower critical solution temperature (LCST) can be precisely controlledExperimental results show that electrodes assembled with this hydrogel achieved a low contact impedanee of20 k(2 at 100 Hz, and the signal-to-oise ratio of the recorded electrocardiogram signals exceeded 28 dB,maintaining funetionality for up to 24 hours. This high -performance hydrogel electrode offers greater potential for the next generation of intelligent physiological signal monitoring and application scenarios.
