Abstract:
1. A device for motivating a medicament through a membrane comprising: an alternating current (AC) signal source capable of providing an electric signal having an orienting frequency or an electric signal having a motivating frequency, or both; at least one non-uniform electrode electrically connected to the AC signal source, where the at least one non-uniform electrode comprises a first irregularly-shaped electrode and a second irregularly-shaped electrode, where the first and second irregularly-shaped electrodes are interdigitated electrodes; where the first and second irregularly-shaped electrodes are electrically connected to the AC signal source; where the first and second irregularly-shaped electrodes define at least one passage to allow an amount of the medicament to pass therethrough; where the first and second irregularly-shaped electrodes describe an equivalent circuit; and where the AC signal source applies an electric signal having an orienting frequency or an electric signal having a motivating frequency, or both, to the equivalent circuit.
