Smart wearable devices can be fabricated using flexible and linear cable-type materials for applications in energy, electronics, sensing and healthcare products. Such wearable devices have been prepared by incorporating conductive nanostructures, metallic nanomaterials, hybrid nanocomposites and polymer nanocomposites on the surface of flexible and permeable cotton materials (threads, fibers, yarns and fabrics). The present research work explores the feasibility of a novel sensor based on nanostructured cotton threads. These threads were functionalized using carbon nanotubes (CNTs) and PANi/...
