摘要： A test sensor includes a body, a first conductive trace, a second conductive trace, and a third conductive trace. The body includes a first region that has a fluid-receiving area, a second region separate from the first region, and a first temperature sensing interface disposed at or adjacent to the fluid-receiving area. The fluid-receiving area receives a sample. The first trace is disposed on the body, and at least a portion of the first trace is disposed in the first region. The second and third traces are disposed on the body. The third trace extends from the first to the second regions. The third trace is connected to the first trace at the first temperature sensing interface. The third trace includes a different material than the first trace. A first thermocouple is formed at the first temperature sensing interface. The thermocouple provides temperature data to determine an analyte concentration.

摘要： An electrochemical test sensor for detecting the analyte concentration of a fluid test sample includes a base, a dielectric layer, a reagent layer and a lid. The base provides a flow path for the test sample having on its surface a counter electrode and a working electrode adapted to electrically communicate with a detector of electrical current. The dielectric layer forms a dielectric window therethrough. The reagent layer includes an enzyme that is adapted to react with the analyte. The lid is adapted to mate with the base and to assist in forming a capillary space with an opening for the introduction of the test sample thereto. At least a portion of the width of the counter electrode is greater than the width of the working electrode.

摘要： A biosensor system determines an analyte concentration of a biological sample using an electrochemical process without Cottrell decay. The biosensor system generates an output signal having a transient decay, where the output signal is not inversely proportional to the square root of the time. The transient decay is greater or less than the −0.5 decay constant of a Cottrell decay. The transient decay may result from a relatively short incubation period, relatively small sample reservoir volumes, relatively small distances between electrode surfaces and the lid of the sensor strip, and/or relatively short excitations in relation to the average initial thickness of the reagent layer. The biosensor system determines the analyte concentration from the output signal having a transient decay.
