ELECTRODE ARRANGEMENTS FOR TEST ELEMENT INTEGRITY

摘要

A method is provided for verifying test element integrity includes providing a biosensor having an electrode-support substrate. A first electrode is provided on the substrate that includes a first body and a neck extending from the first body. A second electrode is provided on the substrate that includes a second body and an opposite pair of necks. Each of the necks extends from a respective end of the second body. A spacer is positioned on the substrate and has an edge defining a boundary of a capillary channel formed between a cover and the substrate. The method also includes applying a signal across the necks of the second electrode to verify continuity along the second electrode. The second body of the second electrode and the pair of connective necks surround the first electrode in the capillary channel forming a loop circuit around the first electrode.

1. A method of verifying integrity test element of a test element having an integrity electrode arrangement, the method comprising:
providing a test element comprising (a) an electrode-support substrate, (b) a first electrode provided on the electrode-support substrate that includes a first body portion and a connective neck extending from the first body portion, (c) a second electrode provided on the electrode-support substrate that includes a second body portion and an opposite pair of connective necks, each one of the opposite pair of connective necks extending from a respective end of the second body portion, (d) a cover, and (e) a spacer coupled to the electrode-support substrate, the spacer including an edge defining a boundary of a capillary channel formed between the cover and the electrode-support substrate, wherein the second body portion of the second electrode and the opposite pair of connective necks surround the first electrode in the capillary channel forming a loop circuit around the first electrode; and applying a signal across the pair of connective necks of the second electrode to verify continuity along the second electrode.
