Claim Text:
1. A system for producing droplet streams having droplets with uniform diameter, the system comprising: a solution dispenser in fluid communication with a fluid reservoir in a fluid reservoir vessel and disposed to maintain the fluid reservoir filled with fluid and under pressure via a channel running substantially parallel to a main axis of the fluid reservoir in the direction of one or more capillary nozzles; a separation membrane defining a first end of the fluid reservoir and in contact with the fluid on one side of the separation membrane; a piezo actuator in contact with the separation membrane on a side opposite that in contact with the fluid; and the one or more capillary nozzles disposed at a second end of the fluid reservoir away from the separation membrane, the fluid within the fluid reservoir contacting both the separation membrane and the one or more capillary nozzles, wherein the one or more capillary nozzles receive fluid from the fluid reservoir and eject a droplet stream from the capillary nozzle.
