Abstract
A circuit detectable arrangement of electrodes and a package thereof are provided so that the presence of a fresh package of electrodes can be detected by a device and can be distinguished from electrodes that have been used or tampered with. A first electrode is disposed on an electrically non-conductive liner, a second electrode is disposed on an electrically non-conductive liner, and an electrical connector is provided between the first and second electrodes for electrically completing a circuit connecting the lead wire of the first electrode to the lead wire of the second electrode. An electrode package is also provided including the first and second electrodes therein. Within the package, the first and second electrodes are provided adjacent to one another with their backing layers generally parallel to one another and with a loop formed in the electrical connector. The loop extends across the tear line and into the interior portion of the package so that by opening the package along the tear line, the electrical connector can be broken. The electrical connector may also include a strip of tear resistant material which is positioned within the interior portion of the package. …
