Abstract
Flexible conductive hydrogels have attracted considerable attention in the field of wearable electronics owing to their unique combination of softness, flexibility, and electrical conductivity. With the increasing demand for personalized healthcare, continuous physiological monitoring, and soft human–machine interfaces, there is a growing need for multimodal sensors capable of detecting diverse signals in real time under dynamic conditions. In this context, multimodal sensing hydrogels capable of detecting mechanical deformation, environmental changes, and physiological signals are regarded as promising materials for next-generation intelligent monitoring systems. However, the development of conductive hydrogels that simultaneously exhibit high stretchability, rapid self-healing capability, excellent conductivity, long-term stability, and reliable sensing performance remains a significant challenge. In this study, a multifunctional poly(acrylic acid) (PAA)-based double-network nanocomposite conductive hydrogel was fabricated for intelligent real-time health monitoring and multimodal sensing applications. The hydrogel can detect both human body movements and electrophysiological signals, demonstrating its potential as a versatile wearable platform for personalized multimodal sensing systems. The stretchability, mechanical strength, adhesiveness, conductivity, and gauge factor of the hydrogel were comprehensively evaluated. Its practical applicability as a wearable sensor was further demonstrated through the real-time monitoring of various human body movements and electrophysiological signals. Therefore, this smart conductive hydrogel-based multimodal sensing platform shows considerable potential for applications in wearable strain sensors, electronic skin, personalized healthcare monitoring, and next-generation flexible electronics.
