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.
