摘要: 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 electrocardiogram (ECG). proposed was fabricated by coating GN on top metallic layer Ag/AgCl using chemical vapour deposition (CVD) technique. To investigate performance GN-based electrode, two types electrodes were with different sizes to conduct signal qualities skin-electrode contact impedance measurements. Performances GN-enabled compared conventional in terms ECG quality, skin–electrode impedance, signal-to-noise ratio (SNR), response time. Experimental results showed produced better signals, higher SNR (improved 8%), lower 78%) values than electrodes.
