However, challenges such as poor mechanical strength, limited sensitivity, and poor durability have hindered the widespread application of PEDOT:PSS hydrogels in high-performance strain sensors. In this study, we develop a novel PEDOT:PSS-P(HEMA-co-AA) hydrogel that addresses common limitations in hydrogel applications, demonstrating remarkable stretchability, low hysteresis, and reliable conductivity. The hydrogel is synthesized using a semi-interpenetrating polymer network (SIPN) strategy, combining the linear conducting polymer PEDOT:PSS with a chemically cross-linked network based on 2-hydroxyethyl methacrylate (HEMA) and acrylic acid (AA). This hybrid structure notably contributes to the hydrogel's mechanical properties, achieving a stretchability of 195 %, while maintaining a rapid response time of 0.20 seconds and exceptional cyclic stability over 1000 cycles under 100 % strain. Moreover, the hydrogel demonstrates promising strain-sensing capabilities, positioning it as a strong candidate for future applications in wearable electronics and flexible sensors.
