Abstract
An apparatus and method are provided, wherein the apparatus includes an electrode and a control circuit. The electrode lacks a corresponding return electrode of opposite polarity on the apparatus. The control circuit is electrically coupled to the electrode and configured to generate and apply to the electrode a voltage having a sinusoidal waveform having at least one step on an edge of the waveform, wherein each step comprises a local peak. The apparatus is arranged to generate an alternating electric field between the electrode and a surface or volume of space in response to the applied voltage.
