Abstract

An electrochemical sensing apparatus and methods are provided. In one embodiment, an apparatus is provided having a carrier that supports an electrochemical module and that communicates between electrodes on the electrochemical module and an analyte measurement device.

Claims

1. A method for manufacturing an electrochemical sensing apparatus, comprising:

providing a carrier having a length dimension and a width dimension, an opening formed in the center of the carrier, and a fold line transverse to the length dimension and extending through the opening;

positioning opposed ends of an electrochemical module on the carrier such that an electrochemical cavity formed in the electrochemical module is positioned across the opening formed in the center of the carrier; and

folding the carrier along the fold line to engage the opposed ends of the electrochemical module between top and bottom portions of the folded carrier and with the remainder of the electrochemical module spanning the opening.

2. The method of claim 1, wherein the electrochemical module includes a first insulating substrate carrying a first electrode that is positioned in electrical contact with a first electrically conductive region on the carrier, and a second insulating substrate carrying a second electrode that is positioned in electrical contact with a second electrically conductive region on the carrier.

3. The method of claim 1, further comprising, prior to positioning, forming first and second electrically conductive regions on the carrier such that the first and second electrically conductive regions are electrically isolated from one another.

4. The method of claim 3, wherein, when the carrier is folded, the first electrically conductive region is on the top portion of the carrier and the second electrically conductive region is on the bottom portion of the carrier.

5. The method of claim 1, further comprising, prior to folding, positioning a spacer on the carrier such that the spacer maintains the top and bottom portions at a distance apart from one another when the carrier is folded.
