Offset electrode
First Claim
1. An electrode comprising:
- a non-conductive substrate having a top surface and at least one channel extending therethrough;
an electrically conductive trace material positioned adjacent at least a portion of the top surface of the non-conductive substrate and extending through said channel, and being adapted to be electrically coupled to a power source;
a second electrically conductive material that is inert or more corrosion resistant than the trace material, the second electrically conductive material being positioned adjacent to and entirely covering a top surface of the trace material,a third electrically conductive material that is inert or more corrosion resistant than the trace material, the third electrically conductive material being positioned adjacent to and entirely covering a top surface of the second electrically conductive material, and covering a portion of the top surface of the non-conductive substrate that surrounds the second electrically conductive material; and
a conductive hydrogel positioned adjacent to a portion of a top surface of the third electrically conductive trace material,wherein the conductive hydrogel is laterally offset from the trace material.

Abstract
An electrode including a non-conductive substrate having a top surface and at least one channel extending therethrough, an electrically conductive trace material positioned adjacent a portion of the top surface of the non-conductive substrate and extending through the channel, and adapted for electrically coupling to a power source, and second and third electrically conductive materials that are inert or more corrosion resistant than the trace material. The second material is positioned adjacent to and entirely covering a top surface of the trace material, and the third material is positioned adjacent to and entirely covering a top surface of the second electrically conductive material, and covers a portion of a top surface of the non-conductive substrate surrounding the second electrically conductive material. The electrode further includes a conductive hydrogel positioned adjacent to a portion of a top surface of the third electrically conductive material, but laterally offset from the trace material.
