For wearable device applications, Au-coated nylon conductive yarns (Au/Nylon) were fabricated by combining supercritical CO₂–assisted catalyzation with electroless plating, using a Ni–P layer as a reactive underlayer for displacement Au plating. The Au coating resulted in lower electrical resistance than that of Ni–P/Nylon yarns regardless of the twist number, demonstrating enhanced conductivity. Electrical resistance was evaluated under loading and unloading conditions to assess conductivity retention under dynamic deformation. SEM and EDS analyses confirmed the deposition of Au on the nylon fiber surfaces.
