A circumferential electrode includes a moisture-containing layer comprising a first side and an electrically conductive layer on the moisture-containing layer, the electrically conductive layer including a second side and a third side opposite the second side, the third side of the electrically conductive layer contacting the first side of the moisture-containing layer. The circumferential electrode further includes a barrier layer on the electrically conductive layer, the barrier layer including a fourth side adjacent to the second side of the electrically conductive layer. The circumferential electrode further includes a bulk region and a border region, the border region completely surrounding the bulk region, and the electrically conductive layer is in the bulk region but is not in the border region. The circumferential electrode can be part of an electrotherapy system which can be used to apply various current waveforms to patients in order to treat a variety of ailments and conditions.
