System and apparatus for determining temperatures in a fluid analyte system
First Claim
1. A test sensor for determining a fluid analyte concentration, comprising:
- a test sensor body including a capillary channel for receiving a fluid sample;
a first temperature sensor located in the capillary channel; and
a second temperature sensor disposed on the test sensor body and located outside of the capillary channel, the first temperature sensor and the second temperature sensor being configured to provide temperature data to assist in determining the fluid analyte concentration or determining an error.

Abstract
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.
