ProcedureA preform was engineered with specific rheological and functional properties. This preform, containing a conductive polymer nanocomposite (polylactic acid, carbon filler, reduced graphene oxide) for temperature sensing and a linear low-density polyethylene passivation layer, was then subjected to a thermal drawing process to create the multi-material fiber. The fiber's temperature sensing performance, including sensitivity, response/recovery times, and durability under mechanical and chemical stress, was evaluated. Finally, the fiber was integrated into a daily cloth and a hand glove to test its performance in a real-world wearable context.
