    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： A thin-film transducer ink jet head is prepared by oxidizing one surface of a silicon wafer to provide a dielectric layer, forming electrodes on the layer by photoresist processing techniques, depositing one or more layers of PZT material to provide a thin-film piezoelectric layer having a thickness in the range of 1-25 microns, forming another pattern of electrodes on the surface of the PZT layer by photoresist techniques, and selectively etching the silicon substrate in the region of the electrodes to provide an ink chamber. Thereafter, an orifice plate is affixed to the substrate to enclose the ink chambers and provide an ink orifice for each of the chambers. An ink jet head having chambers 3.34 mm long by 0.17 mm wide by 0.15 mm deep and orifices spaced by 0.305 mm is provided.
