The functionality of the developed graphene-coated textiles have been demonstrated by non-invasive measurement of electrocardiography (ECG) and electrooculography (EOG) signals. Excellent cross correla- tion of up to 97% was achieved between signals measured with the new textile electrode and that of a commercial silver/silver-chloride (Ag/AgCl) electrode. Our pioneering efforts in this field will be demonstrated by soft, functional nanotextile platforms with embed- ded electronics; otherwise referred to as smart garments, which can be employed in a variety of applications ranging from personalized healthcare to human-computer interaction. nylon cotton polyester SYNTHESIS AND CHARACTERIZATION OF GRAPHENE TEXTILE ELECTRODES G.
