ABSTRACT:
A method and apparatus for forming fluid droplets includes a nozzle channel, a pressurized source of a non-conductive fluid in fluid communication with the nozzle channel, and a stimulation electrode. The pressurized source is operable to form a jet of the non-conductive fluid through the nozzle channel. At least one portion of the stimulation electrode is electrically conductive and contactable with a portion of the non-conductive fluid jet. The at least one electrically conductive and contactable portion of the stimulation electrode is operable to transfer an electrical charge to a region of the portion of the non-conductive fluid jet with the electrical charge stimulating the non-conductive fluid jet to form a non-conductive fluid droplet.
