Abstract
Various systems and methods provide iontophoretic delivery of anesthesia at a patient's tympanic membrane. At least one example is a method including: performing iontophoresis within a first ear canal by driving, by a control unit, a DC signal to an electrode of a first iontophoresis device positioned within the first ear canal, the electrode at least partially submerged within an iontophoresis fluid within the first ear canal; measuring, by the control unit, a mixed capacitance associated with the electrode by driving a first AC signal having a first frequency to the electrode; and determining, based on a change in the mixed capacitance, that an air bubble is present in the iontophoresis fluid.
