Electroencephalography is increasingly used for repetitive applications such as neurofeedback, brain-computer interfaces, and long-term monitoring. Flexible dry electrodes allow rapid preparation and self-application by the user. The electrode shape must easily pass through the hair layer and provide stable, reproducible and comfortable contact with the skin. A common limitation of currently available commercial dry electrodes is the limited contact area of the electrodes and resulting comfort during prolonged application. When used in multi-channel setups, inhomogeneous pressure distribution across the electrode array can lead to spots of excessive pressure, significantly compromising wearing comfort.
Two recent publications address these limitations and demonstrate successful ways to improve the wearing comfort of dry electrodes:
