Phytic acid-mediated polyacrylamide/chitosan/cellulose nanocrystal/PEDOT:PSS composite hydrogels with ion-electron dual conductive pathways for wearable flexible biosensors.
Conductive hydrogels are widely used in flexible sensors for health monitoring. However, current hydrogel sensors face some sustainability challenges, such as unstable conductivity, poor freeze tolerance, rapid dehydration under ambient conditions and limited functionality, significantly hindering their applications.
