1. A method of creating an electrode, comprising:
- providing a substrate having a conductive trace thereon;
applying a first mask over the conductive trace, the first mask having a first opening over a portion of the conductive trace;
applying a material of interest over a portion of the conductive trace and over a portion of the first mask;
applying a second mask over the material of interest, the second mask having a second opening over a portion of the material of interest, the second opening being offset from the first opening; and
applying a membrane material into the second opening over the material of interest, wherein the membrane is of a material that allows molecules to pass at a controlled rate through the second opening to the material of interest.

Abstract
A method of creating an active electrode that may include providing a flex circuit having an electrode made of a first material and providing a first mask over the flex circuit, the first mask having an offset region and an opening that exposes the electrode. The method may also include depositing a second material over the offset region and the opening, the second material being different from the first material and providing a second mask over the second material, the second mask having an opening over a portion of the second material that is over the offset region.
