A Green Electrically Conductive Textile with Tunable Piezoresistivity and Transiency

Abstract A green textile‐based conductor with controllable electrical resistance change deformation and transiency (i.e., dissolution in water) will be the holy grail wearable electronics since it can satisfy divergent needs a single solution sustainable simultaneously. Nevertheless, designing such material is challenging opposite requirements shall satisfied. To solve problem, cotton functionalized using conductive inks made of graphene or carbon nanofiber, biodegradable polyvinyl alcohol binder, environmentally friendly solvents. The shows an anisotropic response to bending depending on composition coating stress direction, functioning either as deformable compliant electrode tunable piezoresistor. Indeed, withstand thousands cycles less than 5% its by many orders magnitude same thanks combination twill different nanofillers. simple modification binder adding waterborne polyurethane allows go from entirely transient water within minutes withstanding simulated washing for hours without losing conductivity. This versatile may serve opposing altering direction.
