Abstract
An electroencephalogram (EEG) sensor is disclosed. The EEG sensor includes a housing defining a chamber capable of storing a gel, the housing includes a first and a second chamber wall, the walls each comprising a corresponding access port located on a common axis extending through the housing; an electrically-conductive probe with a probe tip extending at least partially through the chamber along the axis, at least a portion of the probe tip being exposed to the chamber; an electrical terminal located at an outer surface of the second chamber wall, the electrical terminal being in electrical communication with the probe tip through the access port at the second chamber wall; and a compliant member mechanically coupled to the access port at the first chamber wall capable of compressing, thereby providing a dispense pathway from the chamber through the access port at the first chamber wall.
