Direct spinning of the graphene oxide (GO) dispersions from a moveable spinneret along the programmed track, i.e., a programmable writing technique, was developed to make nonwoven, nonknitted, graphene-based networks with excellent mechanical properties. The resulting GO networks can be successfully converted into reduced GO (RGO) ones with better mechanical properties as well as excellent electrical conductivity via thermal/chemical reduction. In situ welded junctions formed during processing of the spun fibers have made the resulting networks with the integral structure, and outstanding mechanical properties and high electrical conductivities of the spun fibers and their web integrations have provided a great opportunity to remotely sense the external mechanical stimuli via electrical signal monitoring.
