Abstract

This research contributes to the advancement of practical, user-friendly EEG devices for both research and real-world applications. The paper presents a comprehensive study on the development and characterization of wearable electroencephalography (EEG) recording in non-traditional electrode locations. In particular, we focus on optimizing electrode placement, material selection, and signal quality assessment. Our investigation includes impedance testing of various electrode materials, comparative analysis of dry versus wet electrodes, and validation through standard EEG protocols. Results demonstrate the feasibility of acquiring high-quality EEG signals from over-the-ear locations where using gold-plated brush electrodes with retractile pins, show superior impedance characteristics (105Ω) compared to other tested materials. We also validate and compare dry electrodes by means of an eyes-open/eyes-closed protocol, confirming the ability to detect alpha rhythm modulation in non-traditional electrode placements.
