Muscular Activity Monitoring and Surface Electromyography (sEMG) with Graphene Textiles

In this study, we report, for the first time, wearable graphene textile electrodes for monitoring of muscular activity and surface electromyography (sEMG) applications. The feasibility of graphene textiles in wearable muscular monitoring was successfully demonstrated by the acquisition of sEMG signals with wearable graphene textiles, and their performance was benchmarked against commercial, wet Ag/AgCl electrodes. Comparisons were performed in terms of signal-to-noise ratio (SNR), cross correlation and sensitivity to power-line interference. Despite their larger susceptibility to power line interference, graphene textile electrodes displayed excellent similarity with Ag/AgCl electrodes in terms of signal-to-noise ratio (SNR) and signal morphology; with correlation values reaching up to 97 % for sEMG signals acquired from the biceps brachii muscle.
