1. A flexible, electrically-powered iontophoresis apparatus for delivery of an agent through a body surface comprising:

  • a flexible, non-conductive substrate having opposing major surfaces, one of the major surfaces being oriented to face the body surface, the other surface being oriented to face away from the body surface;

    a substantially planar, conductive, electronic pathway disposed on the major surface of the substrate facing the body surface, the electronic pathway including an input means and an output means which are electronically connected, the output means being electrically connected to an electrode means and the input means being electronically connected to a source of electrical energy;

    whereby electrical and physical connection is achieved between the conductive pathway and the electrode in the absence of conductive pathway stress due to folding of the pathway.
