Method and apparatus for using flex circuit technology to create a reference electrode channel
First Claim
1. A method of creating a sensor, the method comprising:
- applying a first conductive material on a first portion of a substrate to form a reference electrode;
depositing a first mask over the substrate, the first mask having an opening that exposes the reference electrode and a second portion of the substrate;
depositing a second conductive material into the opening in the first mask, the second conductive material being in direct contact with the reference electrode; and
depositing a second mask over the second conductive material, the second mask having an opening over the second portion of the substrate, the opening exposing a portion of the second conductive material, which forms a working surface to receive a fluid of interest.

Abstract
A method of creating a sensor that may include applying a first conductive material on a first portion of a substrate to form a reference electrode and depositing a first mask over the substrate, the first mask having an opening that exposes the reference electrode and a second portion of the substrate. The method may also include depositing a second conductive material into the opening in the first mask, the second conductive material being in direct contact with the reference electrode and depositing a second mask over the second conductive material, the second mask having an opening over the second portion of the substrate, the opening exposing a portion of the second conductive material which forms a working surface to receive a fluid of interest.
