Method for making a piezo electric actuator |
摘要 |
A piezo-electric printhead is formed from a first piezo-electric actuator disposed parallel to a second piezo-electric actuator. The first and second piezo-electric actuators have 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. The actuators are formed from a block having a piezo-electric layer disposed on a ceramic base, in which the piezo-electric layer has two parallel, distinct electrode patterns embedded therein in the form of a metal paste.
