ANALYTE TEST STRIP WITH COMBINATION ELECTRODE CONTACT AND METER IDENTIFICATION FEATURE
First Claim
1. An analyte test strip for use with a test meter, the analyte test strip comprising:
- a first insulating layer;
a first electrically conductive layer disposed on the first insulating layer, the first electrically conductive layer including;
at least one electrode portion; and
at least one electrical contact pad configured for an electrical connector pin of a test meter to travel therealong during insertion of the analyte test strip into the test meter, the electrical contact pad in electrical communication with the electrode portion;
at least one meter identification feature disposed on the electrical contact pad such that the electrical connector pin of the test meter travels across the meter identification feature during insertion of the analyte test strip into the test meter;
a second insulating layer disposed above the first insulating layer;
a patterned spacer layer positioned between the first insulating layer and the first electrically conductive layer, the patterned spacer layer defining a sample-receiving chamber therein;
wherein the electrical contact pad has a predetermined contact electrical characteristic value and the meter identification feature has a predetermined identification feature electrical characteristic value that is dissimilar from the predetermined contact electrical characteristic.

Abstract
An analyte test strip (e.g., an electrochemical-based analyte test strip for determining glucose in a bodily fluid sample) for use with a test meter includes a first insulating layer and a electrically conductive layer disposed on the first insulating layer. The electrically conductive layer includes at least one electrode portion and at least one electrical contact pad configured for an electrical connector pin of a test meter to travel therealong during insertion of the analyte test strip into the test meter. In addition, the electrical contact pad is in electrical communication with the electrode portion. The analyte test strip also includes at least one meter identification feature (such as stripes of visually transparent material) disposed on the electrical contact pad such that the electrical connector pin of the test meter travels across the meter identification feature during insertion of the analyte test strip into the test meter. The analyte test strip further includes a second insulating layer disposed above the first insulating layer and a patterned spacer layer positioned between the first insulating layer and the electrically conductive layer that defines a sample-receiving chamber therein. The electrical contact pad of the analyte test strip has a predetermined contact electrical characteristic value and the meter identification feature has a predetermined identification feature electrical characteristic value that is dissimilar from the predetermined contact electrical characteristic.

14. A test meter for use with an analyte test strip, the test meter comprising:
-
a test strip receiving module with at least one electrical connector pin; and a signal processing module, wherein the electrical connector pin is configured to; travel along an electrical contact pad of the analyte test strip during insertion of the analyte test strip into the test strip receiving module; and travel across a meter identification feature disposed on the electrical contact pad during insertion of the analyte test strip into the test meter; and wherein the signal processing module is configured to measure an electrical characteristic via the electrical connector pin as the electrical connector pin travels along the electrical contact pad and across the meter identification feature, and wherein the electrical contact pad has a predetermined contact electrical characteristic value and the meter identification feature has a predetermined identification feature electrical characteristic value that is dissimilar from the predetermined contact electrical characteristic. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
