Abstract: A dielectric transducer for use in a sensor, actuator or generator comprising a plurality of layers of transducer foils, wherein an electrically contactable and conductive layer forming an electrode layer is applied to at least one side of each transducer foil. Expediently, at least two contact elements are provided, each of which is arranged at least partially in a recess or in a through-channel and extends over at least one layer of transducer foils, adjacent electrode layers being electrically conductively connected to different contact elements. Since adjacent electrode layers are connected to different contact elements, intended use is possible, and bringing together several contact lines is advantageously not necessary. Furthermore, the invention relates to a method for producing a multilayer dielectric transducer for use in a sensor, an actuator or a generator, as well as an actuator, a sensor or a generator.

Abstract: A device for determining a condition of a composite component, including: an input interface for receiving measurement data with information on a condition of the composite component; an analysis unit for determining a condition of the composite component based on the measurement data; and an output interface for transmitting the determined condition; wherein the measurement data includes an electrical charge transfer and/or electrical voltage, which can be generated by the composite component through mechanical excitation of the composite component; and the analysis unit is designed and configured to determine the condition of the composite component on the basis of the electrical charge separation and/or electrical voltage. The present invention further relates to a corresponding system and method.
