Abstract: --A piezoelectric transducer including a piezoelectric element and an encapsulation which encloses the piezoelectric element. The encapsulation is configured to set the electro-mechanical properties of the transducer. For example, the hardness of a material of the encapsulation and/or or the geometry of the encapsulation is suitably selected.

Abstract: Summary A dual channel detector is described, wherein the first channel comprises a first sensor and the second channel comprises a second sensor, which are deposited on a substrate. The first and second sensors measure the same physical quantity, but output different measurement signals. The sensors are connected to evaluation units via contact points.

Abstract: In an embodiment a device includes a piezoelectric transducer element and a support connected mechanically to each other thereby forming an assembly, wherein the piezoelectric transducer element and the support are configured to be jointly deformed under an action of a first force, wherein the support includes a neutral fiber arranged inside the support, the neutral fiber configured to not undergo any change in length during a bending of the assembly, and wherein the piezoelectric transducer element includes a ferroelectric polymer layer or a layer having a composite material including a ceramic material and a piezoelectric polymer matrix.

Abstract: A sensor (1) which consists of a first electrode (3a), a ferroelectric layer (2) and a second electrode (3b) is described. The second electrode (3b) is connected to ground and the ferroelectric layer (2) is arranged between the first and second electrodes (3a, 3b).
