    摘要： Systems and methods of ejecting ink drops from an inkjet printer are disclosed. The systems and methods can include a printhead with one or more actuators with associated nozzles and membranes. A voltage waveform can be applied to the actuators to fill the actuators with a volume of ink and eject the ink through the nozzles as ink drops. The voltage waveform can have associated pre-fill voltage to fill the actuator with ink and a firing voltage to eject the ink. The actuator membranes can have multi-height dimples to protect the membranes from contacting electrodes and reduce the electric field.

    摘要： The present application is directed to electrostatic actuators, and methods of making electrostatic actuators. In one embodiment, an electrostatic actuator of the present application can include an electrode layer and a mechanical member. The electrode layer can include a removed portion that is free of a landing pad. The mechanical member can be positioned in proximity to the electrode layer so as to provide a gap therebetween. The mechanical member can further include a dimple structure protruding out into the gap and aligned with the removed portion of the electrode layer. When in operation, the mechanical member can be capable of deflecting toward the electrode layer. The electrostatic actuator can be used in a fluid drop ejector for ink jet recording or printing devices.

    摘要： Implementations relate to methods, devices produced by the method, and systems using the devices, for forming three-dimensional interconnect structures for ink piezoelectric printheads. A piezoelectric element array for an ink jet print head can include a plurality of piezoelectric elements spaced from adjacent piezoelectric elements by an interstitial space. Each piezoelectric element can include a central void space formed in a first intermediate layer between the piezoelectric element array and a second intermediate layer that is operable to function as a free space for portions of the piezoelectric elements to actuate into when subjected to the voltage.
