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

Ferroelectric sensor

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.

Piezoelectric device having a support with a neutral fiber

A dual channel detector. The first channel includes a first sensor and the second channel includes 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.
