First Claim
1. A method of coating an electrode structure with an electrically insulating material, the electrode structure comprising a plurality of electrode pads and a plurality of electrically conducting wires, at least one of the electrically conducting wires extending from at least one of the electrode pads, the method comprising:
- arranging each of the plurality of electrode pads in a first arrangement wherein the electrode pads are located in a single longitudinal row;
arranging the electrically conducting wires relative to each other such that at least some of the electrically conducting wires are adjacent one other and provide a gap of separation between adjacent electrically conducting wires and wherein the electrically conducting wires extend from alternate opposing ends or edges of adjacent electrode pads in the single longitudinal row;
securing the electrically conducting wires to a frame member to preserve said gap of separation between adjacent electrically conducting wires; and
applying a coating of electrically insulating material to said electrode structure,wherein said gap is sufficient to enable said application of said coating of electrically insulating material to all surfaces of said electrically conducting wires without webbing between adjacent electrically conducting wires, and wherein all of the electrode pads in the electrode structure are located in the single longitudinal row.

Abstract
A method of forming electrode structures comprising a plurality of electrode pads and a plurality of electrically conducting wires extending from the electrode pads. The method comprises coating an electrode structure with a relatively electrically insulating material, arranging each of the electrode pads in a first arrangement; arranging the wires relative to each other to provide a sufficient gap of separation between neighboring wires; securing the wires to a remotely positioned anchor member to preserve a gap of separation between neighboring wires, and applying a coating of relatively electrically insulating material to the electrode structure.
