1. A system for delivering one or more active agents to a biological entity under the influence of an inductive power supply, comprising:
- an inductive power supply including a primary winding operable to produce a varying magnetic field; and
an iontophoresis device including at least one active agent reservoir to store the one or more active agents, an active electrode element operable to apply an electromotive force to the active agent reservoir, a counter electrode element, and a secondary winding electrically coupled to the active and the counter electrode elements for providing a voltage across the active and counter electrode elements in response to the varying magnetic field of the inductive power supply;
wherein the iontophoresis device is physically distinct from the inductive power supply.

Abstract
An iontophoresis device for providing transdermal delivery of one or more therapeutic active agents to a biological interface having an active electrode assembly, a counter electrode assembly, and an inductor electrically coupled to the active and the counter electrode assemblies. The inductor is operable to provide a voltage across at the active and the counter electrode elements in response to an applied varying electromagnetic field.
