Abstract
Abstract A biomedical monitoring or stimulating electrode that adheres to a person's skin is disclosed. The electrode is made of a thin, flat flexible material and includes a die-cut patch having one or more adhesive coatings applied on one side of the patch, a foundation component formed into four integral functional areas, a conductive component made up of an electrically conductive material with three contiguous portions, and a conductive media. A connector interfaces with a tab portion of the electrode. The connector includes an electrically conductive element having an inclined surface upon which the tab of the electrode rests. A slider is movable between two positions such that when in its closed position, the electrode neck and head is trapped in the connector and the slider exerts a force on the inclined surface of a cavity of the connector, providing electrical connection to electrode. Thus, the cavity and firm compression act to prevent the electrode from becoming disengaged from the connector.
