摘要： A piezoelectric mechanism includes first and second electrodes and a thin film sheet of piezoelectric material. The second electrode is interdigitated in relation to the first electrode. The first and the second electrodes are embedded within the thin film sheet. The thin film sheet is polarized in a direction at least substantially perpendicular to a surface of the thin film sheet. The thin film sheet is to physically deform in a shear mode due to polarization of the thin film sheet at least substantially perpendicular to the surface of the thin film sheet, responsive to an electric field induced within the thin film sheet at least substantially parallel to the sheet via application of a voltage across the first and the second electrodes.

摘要： A piezoelectric actuator includes a thin film sheet, a first electrode, and a second electrode. The thin film sheet is to physically deform in response to an electric field induced within the thin film sheet. The first electrode is embedded within the thin film sheet. The second electrode is embedded within the thin film sheet, and is interdigitated in relation to the first electrode. The electric field is induced within the thin film sheet via application of a voltage across the first and the second electrodes.

摘要： A method of dispensing a single ligament of fluid includes ejecting a first quantity of fluid from an inkjet dispenser toward a substrate, and ejecting a second quantity of fluid from the inkjet dispenser toward the substrate, wherein the second quantity of fluid is ejected from the inkjet dispenser at a frequency sufficient that the second quantity of fluid catches the first quantity of fluid thereby forming a single ligament of fluid prior to contacting the substrate.
