Electrodes are provided, for example including: (a) a first electrode component including a conductive skin-contacting element, and (b) a second electrode component including a thin electrical conductor. The first and second electrode components may be positioned during storage of the electrode so that the conductive skin-contacting element is not in contact with the thin electrical conductor, and configured so that they can be brought into contact prior to use of the electrode with a surface of the conductive skin-contacting element in contact with a surface of the thin electrical conductor.
