摘要： A piezoelectric ink jet head that includes a polymer film, for example a flex print, located between the piezoelectric element and the reservoirs in the jet body. The film provides an efficient seal for the reservoirs and also positions the electrodes on the side of the piezoelectric element in which motion is effected, which can reduce the magnitude of the drive voltage. This location of the compliant flex print material also can enhance electrical and mechanical isolation between reservoirs, which improves jetting accuracy. The compliance of the polymer also reduces strain on the ink jet head.

摘要： Techniques are provided for forming nozzles in a microelectromechanical device. The nozzles are formed in a layer prior to the layer being bonded onto another portion of the device. Forming the nozzles in the layer prior to bonding enables forming nozzles that have a desired depth and a desired geometry. Selecting a particular geometry for the nozzles can reduce the resistance to ink flow as well as improve the uniformity of the nozzles across the microelectromechanical device.

Devices include a flow path that includes a pumping chamber in which fluid is pressurized for ejection of a fluid drop, and a semi-permeable membrane including an inorganic material having an outer surface positioned in fluid contact with the flow path. The membrane allows gases to pass therethrough, while preventing liquids from passing therethrough.
