Comparison of Ag/AgCl and Au EEG Cup Electrodes: A Scientific Literature Review
By Amy Banks
Abstract The scientific literature provides evidence comparing silver/silver chloride (Ag/AgCl) and gold (Au) electrodes for EEG procedures. Research demonstrates that Ag/AgCl electrodes consistently outperform gold electrodes in terms of signal quality, noise characteristics, and response at low frequencies, while gold electrodes offer superior durability and biocompatibility. The selection between electrode materials requires balancing signal performance … Continued
