摘要：Hydrogels have recently attracted considerable attention within the field of flexible electronics, given their potential for utilization in a multitude of applications. Among the various hydrogel formulations, those incorporating conductive polymers have emerged as highly promising materials for sensor applications, due to their enhanced electrical and mechanical properties. This study is concerned with the development of a novel hydrogel system comprising conductive polymers (poly (3,4-ethylenedioxythiophene:polystyrene sulfonate, PEDOT:PSS)) based on hydroxyethyl cellulose (HEC) templates and polyacrylamide (PAM), which are combined to produce robust double-network hydrogel. The conductive component obtains good homogeneity and conductivity low EDOT content, and accordingly, the PEDOT:PSS@HEC/PAM hydrogels obtained therefrom possess excellent mechanical with the elongation at break of 1060%, tensile strength of 463 kPa and a high GF of 7.35. The system is capable of providing real-time, accurate, and stable feedback on the changes of various physical and physiological indicators of the human body, including joint activity, vocal cord vibration, electrocardiogram, electromyogram, among others. This suggests promising applications for flexible electronic signal detection sensing systems.
