Flexible and conductive hydrogels play an important role in the design and fabrication of wearable sensors. However, the preparation of high-performance hydrogel-based sensors that can work under extreme cold conditions is still challenging. Herein, we demonstrated the preparation of a novel composite hydrogel based on polyacrylamide (PAM), LiCl, and PEDOT:PSS coated cellulose nanofibrils (PEDOT:PSS/CNF). The introduction of PEDOT:PSS/CNF increased the hydrogen bonding between the molecular chains in the micro and enhanced the mechanical strength and the conductivity of the hydrogel in the macro. Moreover, the presence of LiCl endowed the hydrogel with excellent freezing tolerance. For example, the optimized hydrogel exhibited stable mechanical properties at extreme cold conditions (e.g., −40 ℃). Finally, the composite hydrogel was used to assemble a flexible sensor, which could detect a wide range of human movement and physiological activities in a stable, fast, and accurate manner. Overall, this work provided a simple and universal approach for the preparation of flexible and anti-freezing hydrogels that can be used for flexible electronic devices.
