摘要： Methods, systems, and apparatus for drive a pumping chamber of a fluid ejection system are disclosed. In one implementation, the actuator for drive the pumping chamber includes a continuous piezoelectric layer between a pair of drive electrodes and a continuous reference electrode. The pair of drive electrodes includes an inner electrode and an outer electrode surrounding the inner electrode. The actuator is further coupled to a controller which, during a fluid ejection cycle, applies a negative voltage pulse differential to the outer electrode to expand the pumping chamber for a first time period, then applies another negative voltage pulse differential to the inner electrode during a second time period after the first time period to contract the pumping chamber to eject a fluid drop.

摘要： A fluid ejection apparatus includes a substrate having a nozzle surface and a passage through the substrate for fluid flow, the passage having a nozzle that includes an opening in the nozzle surface of the substrate, and an actuator to cause fluid in the passage to be ejected from the nozzle. The nozzle includes side walls extending away from the opening, the side walls sloping outwardly as the side walls extend away. An aspect ratio of a length of the opening to a width of the opening is at least 2:1.
