Abstract
An electrochemical test sensor includes a base, a generally hard electrically-conductive layer, an electrochemically-active layer, and a lid. The electrically-conductive layer is located between the base and the electrochemically-active layer. The electrically-conductive layer and the electrochemically-active layer are made of a different material. The electrically-conductive layer and the electrochemically-active layer form an electrode pattern. The electrochemical test sensor includes a reagent adapted to assist in determining information related to an analyte of a fluid sample.
