Abstract:
1. An iontophoretic device comprising: an electrical channel having first and second sides; at least three electrodes, with at least two electrodes coupled to the first side and at least one electrode coupled to the second side, wherein each of the at least two first side electrodes electrically communicates with the at least one second side electrode; a controller that generates a control signal responsive to a first feedback signal indicative of current flowing through a first regulator and a second feedback signal indicative of current flowing through a second regulator, wherein each of the first and second regulators is coupled between an associated one of the at least three electrodes and the controller; a power source operatively connected to the controller and the first and second regulators; and, wherein, for each of the first and second regulators, a regulated current flows through both that regulator and its associated one electrode in response to the control signal.
