Abstract:
1. A flat multilayered component for use as an actuator or sensor, the flat multilayered component comprising: a layer of electrically activatable material; a passive middle layer disposed adjacent said layer of electrically activatable material; a further passive material layer disposed adjacent said passive middle layer, said passive middle layer having a higher coefficient of linear thermal expansion than both of said layer of electrically activatable material and said further passive material layer, wherein said layer of electrically activatable material has a first thickness and said further passive material layer has a second thickness, and wherein a ratio of the first thickness and the second thickness is such that about the same mechanical expansion occurs in said layer of electrically activatable material and said further passive material layer for a given change in an operating temperature of the flat multilayered component and wherein the passive middle layer and the further passive material layer are formed of metal.
