Abstract: In accordance with at least one aspect of this disclosure, an encephalographic electrode assembly can include a wicking element that has a wick body, one or more long legs extending from the wick body and inserted into the one or more hollow contact probes, and one or more short legs, which are shorter than the long legs, extending from the wick body and inserted into the one or more short reservoir sleeves. The short legs are configured to prevent slide-out of the wicking element from the reservoir body.

Abstract: An electrode assembly can include a reservoir defining a plurality of openings on a first surface of the reservoir, a wicking material extending through one or more of the plurality of openings, and a conductive terminal. An electrode assembly can include a reservoir cap, a reservoir bottom configured to fit to the reservoir cap and define a reservoir therewith, an electrode disposed within the reservoir, and a wicking element in electrical communication with the electrode and configured to absorb a fluid, wherein at least a portion the wicking element is configured to protrude from the reservoir bottom.
