EEG ELECTRODES WITH GATED ELECTROLYTE STORAGE CHAMBER AND AN ADJUSTABLE EEG HEADSET ASSEMBLY

摘要

A confined dry scalp EEG sensor design couples an electrode and skin electrically with a confined electrolyte solution. The electrolyte solution is confined inside the EEG sensor when the sensor is not in use. When in use, the electrolyte solution extends from the sensor to contact the skin and form a sensor probe-skin interface. The EEG sensor may be placed in headset assembly for holding the EEG sensor against the skin. The headset assembly may have an adjustable length and adjustable tension to form a comfortable fit on the skin. The EEG sensor may be integrated with an optical apparatus for multimodal neural sensing or stimulation through the skin.
