    摘要： A piezoelectric actuator includes a cantilever membrane. A thin film sheet is affixed to one side of the cantilever membrane to bend the membrane in multiple directions in response to an electric field induced within the thin film sheet. A plurality of coplanar electrodes disposed on the thin film sheet are interdigitated in relation to one another to generate the electric field during application of a voltage across interdigitated electrodes.

    摘要： Disclosed is an inkjet print head array with improved ink supply system. The system includes an ink manifold having at least two ink supply channels, a plurality of print head modules disposed along ink supply channels and forming the array, with each of the print head modules having at least two ink inlet ports. The ports are in fluid communication with the ink supply channels. Each of the ink supply channels supplies ink to each of the ports at a different flow rate, although the resulting ink supply flow rate is equal for each print head module.

    摘要： An ink jet print head includes a silicon ink jet chip, a print head holder, configured to carry and support the silicon chip, and a glass plate, bonded between the silicon chip and the print head holder. The ink jet chip has a coefficient of thermal expansion αs. The print head holder has a holder wall thickness, and a coefficient of thermal expansion αh that is substantially different from αs. The glass plate has a coefficient of thermal expansion αg that is substantially similar to αs, and a thickness at least as great as the holder wall thickness, whereby stress created by differential thermal expansion between the silicon chip and the holder is attenuated by the glass plate.

    摘要： An electro-wetting-on-dielectric printing system includes a drum and an electrode array disposed on a surface of the drum, which is made up of individually addressable electrodes and an ink-phobic coating overlaying the electrodes. Electrically charging a portion of the electrodes allows ink to adhere to a portion of the ink-phobic coating in proximity to the charged electrodes. A method for electro-wetting-on-dielectric printing includes selectively charging individually addressable electrodes within an electrode array, and passing the electrode array through an ink bath, wherein ink adheres areas proximate to charged electrodes to form an image. The image is then transferred to the substrate.
