Abstract
Abstract Electrode assembly for transcutaneous neural stimulation comprising a first layer of non-conductive knit fabric material; a flexible, generally flat electrically conductive electrode in confronting relationship with a portion of the fabric material; a second layer of non-conductive material overlying the upper surface of the electrode and dimensioned to extend beyond the periphery of the electrode; means for securing the second layer to the first layer to confine the electrode therebetween and define a generally flat pocket between the electrode and first layer, the pocket operable to receive a conductive fluid therein; and means defining a boundary around the periphery of the electrode for preventing migration of the conductive fluid beyond the periphery of the electrode.
