ABSTRACT:
An improved nozzle modulator, an improved nozzle modulator assembly, and an improved coating method comprises a nozzle having a housing. A fluid reservoir communicates with the housing. The nozzle has a nozzle outlet about which a meniscus is formed. A high voltage source is connected to the nozzle. The fluid is dispensed as one or more charged fluid paths from the nozzle upon the actuation of the high voltage source. A plurality of repulsive and attractive electric fields are positioned to surround the fluid path. An electrical biasing means is connected to the electrical fields for biasing the fields and modulating the fluid path to form a homogeneous fog comprising uniformly disbursed droplets moving in a wide variety of directions.
