Abstract
Electrokinetic transducing methods and systems are disclosed in which the two electrode arrays confront each other and each electrode in one array is equidistant from the two nearest electrodes in the other array. The electrode arrays are excited by pulsed exciting voltages, the individual pulses of which are preferably all negative or all positive, have durations equal to or less than the pulse intervals, and have rounded leading knees. Embodiments of the invention are disclosed for applications including electrokinetic loudspeakers, ion generators, fans, and electrostatic precipitators.
