An electrostatic atomizer electrostatically atomizes a fluid into a charged spray, wherein the charged spray includes a plurality of charged droplets. The electrostatic atomizer includes a chamber forming an inlet and an exit aperture, wherein the chamber is configured for fluid to flow into the chamber from the inlet and to flow out of the chamber from the aperture. An emitter electrode is in liquid contact with the fluid in the chamber and injects an electrical charge into the fluid in the chamber. An impedance circuit is coupled to the chamber and configured to obtain a voltage difference between the emitter electrode and the exit aperture, wherein the voltage difference is at least a minimum voltage threshold.
