Abstract: | The unique parameters of Graphene (GN), notably its considerable electron mobility, high surface area and electrical conductivity are bringing extensive attention into the wearable technologies. This work presents a novel Graphene-based electrode for acquisition of electrocardiogram (ECG). The proposed electrode was fabricated by coating GN on top of metallic layer of Ag/AgCl electrode using chemical vapor deposition (CVD) technique. To investigate the performance of the fabricated GN-based electrode, two types of electrodes were fabricated with different sizes to conduct the signal qualities and the skin-electrode contact impedance measurements. Performances of the GN-enabled electrodes were compared to the conventional Ag/AgCl electrodes in terms of ECG signal quality, skin-electrode contact impedance, signal-to-noise ratio (SNR) and response time. Experimental results showed the proposed GN-based electrodes produced better ECG signals, higher SNR (improved by 8%) and lower contact impedance (improved by 78%) values than conventional ECG electrodes. |
