A bioelectrode for non-invasive and inotophoretic delivery of chemical species (such as ions, polar molecules, etc.) into the skin of a person. The bioelectrode includes a pouch having flexible walls, at least a portion of which is composed of a microporous, permeable or semipermeable membrane. The pouch holds fluid which contains the chemical species to be delivered through the skin. An electrode is attached to the pouch so that when the pouch is placed against the skin, with the membrane portion in contact with the skin, and an electric potential is applied to the electrode, chemical species in the pouch are caused to migrate through the membrane and into the skin.

A bioelectrode for use in the iontophoretic delivery of a chemical species into the skin or tissue of a person comprising a pouch for holding a fluid containing the chemical species, said pouch including flexible and deformable walls adapted to generally conform to surface shapes against which they are placed, at least a portion of which includes a microporous membrane separating the interior of the pouch from the exterior and having openings of about 0.22 microns or less in diameter, said portion being formed to present a generally planar to convex exterior surface, and an electrode carried by said pouch for coupling to an electric potential source.
