First Claim
1. An electrochemical-based analytical test strip for the determination of an analyte in a bodily fluid sample, the electrochemical-based analytical test strip comprising:
- an electrically insulating base layer; and
a patterned conductor layer disposed over the electrically-insulating layer, the patterned conductor layer including at least one electrode,wherein the at least one electrode has electrochemically inert areas, an electrically continuous electrochemically active area lattice, and non-conductive border regions separating the electrochemically inert areas and the electrically continuous electrochemically active area lattice, the electrochemically inert areas and the at least one electrochemically active area being of a predetermined size and a predetermined distribution such that electrochemical response of the electrode during use of the electrochemical-based analytical test strip is essentially equivalent to a predetermined electrochemical response of a different electrode.

Abstract
An electrochemical-based analytical test strip for the determination of an analyte (e.g., glucose) in a bodily fluid sample (such as a whole blood sample) includes an electrically insulating base layer and a patterned conductor layer (for example, a gold patterned conductor layer) disposed over the electrically-insulating layer. The patterned conductor layer includes at least one electrode with the electrode having electrochemically inert areas and an electrochemically active area(s). Moreover, the electrochemically inert areas and electrochemically active area(s) are of a predetermined size and a predetermined distribution such that electrochemical response of the electrode during use of the electrochemical-based analytical test strip is essentially equivalent to a predetermined electrochemical response.
