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. | |
