ABSTRACT:
A method of manufacturing actuators for an inkjet head includes the step of measuring an absolute value of a coercive voltage of an active layer. The method further includes the step of sorting the actuators based at least on the coercive voltage. Each of the actuators includes a first electrode, a second electrode, an active layer positioned between the first electrode and the second electrode, and an inactive layer wherein the second electrode is positioned between the inactive layer and the active layer.
