Elastic neural electrode and method for fabricating the same

Method for fabrication of an elastic neural electrode, comprising the following steps:

• applying an elastomer layer onto a release carrier;
• structuring the elastomer layer using a laser beam;
• laminating at least one metal layer onto the elastomer layer;
• structuring the at least one metal layer using a laser beam;
• removing excess metal;
• applying an elastomer layer onto the at least one metal layer, thus defining an edge to a welding area;
• locally applying a masking tape at the welding area;
• deposing a high-tensile-strength polymer layer directly onto the at least one metal layer, and onto the elastomer layer, and onto the masking tape;
• structuring openings and cutting-free the masking tape using a laser beam;
• removing the masking tape, thus exposing the welding area;
• removing the electrode from the mechanical carrier;
• welding wires to the electrode at the welding area;
• sealing the welding area with an elastomer adhesive.
