Title
EEG Measurement Using Dry Electrodes Comprising Two-layered Conductive Silicone with Different Carbon Concentrations.
Abstract
Electroencephalography (EEG) typically involves the use of wet electrodes, which are inconvenient and impair signal quality. In this study, we propose a new electrode comprising two-layered conductive silicone with different carbon concentrations as a non-metallic flexible EEG electrode. The proposed electrode was shown to function as an EEG electrode while maintaining its superior flexibility compared to nonmetallic dry electrodes, such as carbon-containing polymer electrodes. Moreover, we hypothesized that the signal quality varies with carbon concentration and contact area, and thus compared the signal correlation coefficient and SNR with that of the wet electrode for 20 sets of electrodes: 15 sets with the carbon:silicone weight ratio ranging from 1.7% to 3.1%, and 5 sets with the electrode diameter in the range 8–18 mm. We observed that the signal quality of the proposed electrode was closest to that of the wet electrode when the carbon:silicone weight ratio was 2.6%–2.8% and the diameter was 8–10 mm. Our results suggest that the proposed electrode is a viable gel-free non-metallic flexible electrode and is suitable for daily use.
