Abstract
A method for forming an Ag/AgCl coated electrode includes providing a polymeric electrode substrate made of Acrylonitrile Butadiene Styrene (ABS). A layer of silver (Ag) is deposited on the polymeric electrode substrate using physical vapor deposition (PVD) to form an Ag coated electrode. The layer of Ag is deposited to a first thickness by sputtering an Ag target onto the polymeric electrode substrate. The Ag coated electrode is then converted to a layer of silver/silver chloride (Ag/AgCl) by dipping it into a conversion solution. The resulting Ag/AgCl coated surface electrode provides improved performance and stability for various applications.
Core Innovation
The invention describes forming an Ag/AgCl-coated neuromonitoring electrode on a polymeric substrate comprising ABS. A silver layer is deposited on the substrate by physical vapor deposition using sputtering, and the silver layer is converted to a silver/silver chloride layer. The conversion-solution composition and conditions are [procedural detail omitted for safety].
Electroless plating serves as a point of comparison for the described manufacturing process. The described manufacturing approach reduces hazardous waste, environmental impact, and manufacturing costs. Background details explaining the specific need for the invention are not explicitly described in the patent.
