摘要
Conductive hydrogels have attached considerable attention due to their good stretchability,excellent conductivity when they are applied in soft electronics. However,to fabricate a flexible hydrogel sensor with excellent toughness and good self-healing properties remains a challenge. In this work,we assembled a dual physical-crosslinking(DPC) ionic conductive polyacrylamide/carrageenan double-network(DN) hydrogel. This hydrogel has excellent fracture tensile stress and toughness,and demonstrates rapid self-recovery and self-healing ability due to the unique dual physical-crosslinking structures. Besides,the hydrogel is highly conductive by adding some conductive ions. As a result,the hydrogel-based sensor can stably detect human motions and physiological signals. The work provides novel ideas for the development of flexible sensing devices.
