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.
Claims16
A device comprising:
- 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,
