    摘要: A piezo actuator with protection against environmental influences comprises a layer stack (1) of piezoelectric material layers (10) and interposed electrode layers (20). The piezo actuator furthermore comprises a first and a second material layer (31, 32) composed in each case of a material which exhibits smaller amount of expansion. than the piezoelectric material layers (10) when a voltage is applied. to the electrode layers (20), and comprises a cover layer (50) composed of a metal material. The layer stack (1) is arranged between the first and second material layers (31, 32). The cover layer (50) surrounds the layer stack (1) and is sputtered onto the first and second material lavers (31, 32).

    摘要: A microphone includes a first diaphragm and a second diaphragm coupled to the first diaphragm by a closed air volume. The first diaphragm and the second diaphragm each constitutes a piezoelectric diaphragm. The first diaphragm and the second diaphragm are electrically coupled so that movement of the first diaphragm causes movement of the second diaphragm.

    摘要: The SAW component has electrical structures which are encapsulated and sealed against environmental influences by a cap cover. Connecting pads of the electrical structures are exposed in a window of the cap cover and the pads are provided with a metallization. Solderable metallized areas are formed on the cap cover, and they are connected to the pad metallizations via through-plated holes.
