One or more electrodes of an iontophoresis device may include a composite
ion exchange membrane comprising a first ion exchange membrane of a first
polarity and a second ion exchange membrane of a second polarity, or a
first ion exchange membrane of the first polarity, a semi-permeable
membrane, and a second ion exchange membrane of the second polarity. The
respective membranes may be integrally coupled together. This may lead to
simplified production processes, automated production, mass production,
and reductions in production costs for the iontophoresis device.
