A piezo electrical component has a stack of piezo electrical layers arranged over each other and electrode layers arranged therebetween. The stack has at least one first piezo electrical layer having a first piezo electrical charge constant and, directly adjacent thereto, at least one second piezo electrical layer having a second piezo electrical charge constant. The piezo electrical charge constant describes an expansion of the piezo electrical layer perpendicular to an electrical field at a voltage 6 applied to the electrode layers. The first piezo electrical charge constant is different from the second piezo electrical charge constant. |
