PT-PLATING METHOD FOR POLYIMIDE ELECTRODE

摘要

PURPOSE: A platinum plating method for a polyimide electrode is provided to produce a polyimide electrode capable of accurately measuring bio-signals of micro current by reducing the impedance. CONSTITUTION: A platinum plating method for a polyimide electrode is as follows. A conductive seed layer is washed in sulfuric acid solution before electroplating(S3). The gases in contact with the conductive seed layer surface are eliminated through ultrasonic wave while carrying out electroplating with an electric current density of 2.0 Ma/cm^2 for 2 minutes(S4).
