ELECTROCHEMICAL SENSORS AND A METHOD FOR THEIR MANUFACTURE

摘要

The invention provides electrochemical-based modules useful for the determination of an analyte in a bodily fluid sample. The modules of the invention provide opposed electrodes, but the contact areas for making electrical contact between the electrodes and the analyte measurement device are coplanar.

主权项

1. An electrochemical module, comprising:
a first substrate having a first conductive layer thereon and forming a first substrate-conductive layer assembly wherein the assembly has a first width and a first length; a second substrate having a second conductive layer thereon and forming a second substrate-conductive layer assembly wherein the assembly has a second width that is less than the first width and a second length that is substantially the same as the first length wherein the first and second conductive layers are in a facing relationship; a first and a second spacer disposed between the first and second assemblies and maintaining the assemblies in a spaced apart relationship; a chamber formed between the first and second assemblies and configured to receive a fluid sample, wherein the chamber comprises a reagent capable of reacting with an analyte in the fluid sample; and and a third spacer adjacent to one of the first or second spacers, a surface of the third spacer comprising a conductive layer that is in electrically conductive contact with the second conductive layer.
