A bioelectrode for use in the iontophoretic delivery of ions into the skin or tissue of a person includes either a receptacle or a composition of material suitable for holding ions to be delivered, a metallic foil disposed on one side of the receptacle or composition of matter, and a coupling device for electrically coupling the foil to an electrical source. The other side of the receptacle or composition of material is for placement against a person\s skin or tissue so that ions may be delivered thereinto. The receptacle or composition of material both include features or characteristics which inhibit the migration of ions laterally therein, i.e., in a direction generally parallel to the surface of the skin or tissue, but which allow migration in a direction generally perpendicular to the surface of the skin or tissue, and in particular from the metal foil toward the person\s skin or tissue. The advantage of this capability is to provide a substantially uniform movement of ions into the skin or tissue over surface area of contact of the bioelectrode with the skin.

A bioelectrode for use in the iontophoretic delivery of ions into the skin or tissue of a person comprising means holding ions to be delivered, one side of which is for placement against the person\s skin or tissue, said holding means being adapted to inhibit movement of ions in a direction generally parallel to the surface of the skin or tissue, an electrically conductive sheet of material disposed at a substantial portion of the other side of said holding means, and means for coupling said sheet of material to an electrical source.
