    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 thermal fluid-ejection mechanism includes a substrate having a top surface. A cavity formed within the substrate has one or more sidewalls and a floor. The angle of the sidewalls from the floor is greater than or equal to nominally ninety degrees. The thermal fluid-ejection mechanism includes a patterned conductive layer on one or more of the substrate's top surface and the cavity's sidewalls. The thermal fluid-ejection mechanism includes a patterned resistive layer on the sidewalls of the cavity. The patterned resistive layer is located over the patterned conductive layer where the patterned conductive layer is formed on the sidewalls of the cavity. The patterned resistive layer is formed as a heating resistor of the thermal-fluid ejection mechanism. The conductive layer is formed as a conductor of the thermal-fluid ejection mechanism, to permit electrical activation of the heating resistor to cause fluid to be ejected from the thermal fluid-ejection mechanism.
