Zusammenfassung: | A piezoelectric actuator comprises a substrate, an insulator layer on the substrate, and a piezo actuator stack on the insulator layer. The piezo actuator stack comprises an insulator-adjacent electrode on the insulator layer. A piezo layer having a tapered sidewall resides on a portion of the insulator-adjacent electrode. An insulator-distal electrode on the piezo layer having a taper-adjacent edge offset from an intersection of the tapered sidewall of the piezo layer and the insulator-adjacent electrode. |
