摘要： The invention relates to a thermoelastic energy converter (1), in particular for use in a thermoelastic heating/cooling apparatus or in a combined heat-and-power coupling system, comprising:
an arrangement comprising multiple converter devices (3a, 3b), wherein each of the converter devices (3a, 3b) has one or more thermoelastic elements (4) arranged in a direction of extension;
a loading device, in order to load the thermoelastic elements (4) of each of the multiple converter devices (3a, 3b) so as to have a temporally variable power curve;
a coupling which is designed such that the loading device actuates the converter devices (3a, 3b) in a phase-offset manner with respect to their cyclic loading and unloading.-

摘要： 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.

摘要： The invention relates to an actuator (1; 1a; 1b) which can be moved from an initial position into a working position having at least one actuator element (2; 2a; 2b) whose dimensions can changed by an electrical signal, Appropriately, at least two restoring means (20, 30; 20a, 30a; 20b, 30b) acting on the actuator element (2; 2a; 2b) are provided for movement into the working position. With the at least two restoring means, a total restoring means characteristic curve, which is composed of portions of the individual, preferably preloaded restoring means as well as a portion of a variable stiffness of the actuator element, can be advantageously tailored.
