Abstract

The present invention relates to a physiological recording electrode, and, more particularly, to an EEG (electroencephalography) recording electrode that can be used without the need for numerous steps in preparing the subject's skin and the electrode itself. The invention further relates to a surface feature or penetrator with a size and shape which that will not bend or break, which limits the depth of application, and/or anchors the electrode or other device during normal application; and a packaging system comprising a well and electrolytic fluid for maintaining a coating of said electrolytic fluid on the surface feature or penetrator.

Core Innovation

The invention describes a physiological recording device with a packaging base layer including at least one well containing an electrolytic fluid, gel, colloidal suspension, or colloid. At least one electroencephalography (EEG) physiological recording electrode has an upper surface and a lower surface, and the lower surface includes at least one surface feature protruding from the lower surface and at least partially coated in a conductive material or substance.

The conductive material or substance and/or the surface feature is at least partially coated in an electrolytic fluid from the well in the packaging base layer. The electrolytic fluid and the conductive material or substance are chosen to maintain a surface attraction such that the electrolytic fluid and conductive material or substance are attached or attracted to each other on the at least one surface feature.

The disclosed embodiments further include porous media in the well, such as sponge or colloid, that maintains a coating of electrolytic fluid on the penetrators during storage. The electrode and packaging incorporate adhesive collars for attachment and removal, and various surface feature geometries are disclosed, including ridges, columns, anchors, epidermal stops, and detritus troughs.

Claims Coverage

The claims coverage identifies one main independent inventive coverage with four inventive features centered on an EEG physiological recording device and its packaging base layer.

Overall, the claim coverage centers on an EEG physiological recording device that combines a well-contained electrolytic material in a packaging base layer with an EEG electrode whose protruding lower-surface feature carries a conductive material coating and is also at least partially coated by electrolytic fluid from the well, with the electrolytic fluid and conductive material selected to maintain surface attraction.
