  • Spray electrode
    Patent number: 8490898
    Abstract: An electrostatic spraying device comprises a capillary spray electrode having a spraying end, a reference electrode, and a reservoir in fluid communication with the spray electrode. In use, the electrodes are connected across a generator in order to establish an electric field between the electrodes and cause fluid in the reservoir to be sprayed from the spray electrode. The spray electrode has a focus that defines a point at which the electric field is focussed on the spraying end.
