Abstract:
A piezo-electric printhead comprising:a first piezo-electric actuator disposed parallel to a second piezo-electric actuator, the first and second piezo-electric actuators being disposed on a base and having a shared inner electrode disposed between them, a first control electrode disposed on an outside surface of the first piezo-electric actuator and a second control electrode disposed on an outside surface of the second piezo-electric actuator, each the first and second piezo-electric actuators being formed from an array of actuators arranged in first and second columns, the first and second columns being parallel to one another and separated from one another by a first dice formed to a first depth, each of the actuators of the first array and each of the actuators of the second array being separated from other actuators of that array by a second dice formed to a second depth different from the first depth, and formed transverse to the first dice.
