Methods, and devices produced by the methods, for electroplating a multitude of micro-scale electrodes that are electrically isolated from each other on a cable or other device is described. A localized area of connections on another end of the cable is shorted together by depositing a metal sheet or other conductive material over the localized area. The metal sheet is connected to a terminal of a power supply, and the electrode end of the cable is immersed in an electrolyte solution for electrodeposition by electroplating. After the electrodes are electroplated, the metal sheet is removed from the cable in order to re-isolate the electrodes.
