摘要： An electrohydrodynamic (EHD) jet printing apparatus or system may include circulation of printing fluid to minimize or eliminate clogging in a nozzle. An exemplary nozzle comprises at least two ink channels— one allowing flow to a droplet emitting opening and one allowing flow away from the droplet emitting opening— configured for circulating ink. The nozzle may transfer ink to a substrate with an EHD technique involving voltage or current modulation. For example, an electric field may be applied between the nozzle and printing substrate such that the ink meniscus changes shape and releases ink from the tip of the liquid cone. A multi-channel nozzle may take a variety of configurations, including two co-axially aligned capillaries, side-by-side parallel capillaries, or capillaries arranged at an angle with respect to one another but converging at a single point where the conical meniscus is formed.

摘要： For printing, the principle of the continuous deflected jet is used: a device (1) discharges a continuous stream (2) of a conductive liquid, which is deflected by an electric field created by a deflecting electrode (8) and directed toward a gutter (6). The printing of drops (12) is performed by fragmenting the continuous jet (2) into a segment (10) formed opposite a shield electrode (14) upstream of the deflecting electrode (8), so that the segment (10) is not deflected and can be directed toward a substrate (16).

摘要： A method for the electrohydrodynamic deposition of carbonaceous materials utilizing an electrohydrodynamic cell comprising two electrodes comprised of a conductive material, by first combining a solid phase comprising a carbonaceous material and a suspension medium, placing the suspension between the electrodes, applying an electric field in a first direction, varying the intensity of the electric field sufficiently to drive lateral movement, increasing the electrical field to stop the lateral transport and fix the layers in place, then removing the applied field and removing the electrodes. Among the many different possibilities contemplated, the method may advantageously utilize: varying the spacing between the electrodes; removing the buildup from one or both electrodes; placing the electrodes into different suspensions; adjusting the concentration, pH, or temperature of the suspension(s); and varying the direction, intensity or duration of the electric fields.

摘要： An apparatus provides precise steering of inkjet droplets to a substrate by use of multipole arrangement with electrodes (1-4) on a resistive plate (6). There may be droplet detection based on charge sensing. A hexagonal spiral deposition pattern on a target substrate (7) allows fast uniform printing covering a nearly circular hexagonal area. There may be six electrodes (210-215) arranged to form a cubic enclosure, and injected droplets may be merged within the enclosure, and their charge controlled by merging of source droplets of differing charges to provide a net charge for biasing onward steering.

摘要： An electrohydrodynamic printer has a fluidic extractor. A stream of liquid or carrier fluid at a different electrical potential than the printing fluid passes by an extraction opening to extract printing fluid from the extraction opening. The stream of liquid can be a continuous stream, a uniform stream of droplets, or a non-uniform stream of droplets. The extracted printing fluid can merge with the extraction fluid to be carried to a printing surface for deposition. The stream of extraction fluid can be intermittently charged to intermittently extract printing fluid such that selective portions of the stream do not extract printing fluid.
