Title:
音響泳動印刷における音響泳動力の調節
Document Type and Number:
Japanese Patent JP7361049
Kind Code:
B2
Abstract:
The method comprises arranging a nozzle having a nozzle opening within a first fluid, and generating an acoustic field in the first fluid by an oscillating emitter. A second fluid (an "ink") is driven out of the nozzle, thereby forming a pendant droplet of the second fluid at the nozzle opening. The acoustic field at the nozzle opening is modulated, and acoustic forces from the acoustic field promote detachment of the pendant droplet. Thus, the second fluid or ink is controllably ejected in the first fluid as an ejected droplet. For acoustophoretic printing, the nozzle opening may be positioned in opposition to a printing substrate, and the ejected droplet may be deposited on or in the printing substrate.
