摘要： A pressure sensor has a multiplicity of piezoelectric converter elements which are arranged such that they are essentially parallel to a force-applying or pressure-applying direction. The converter elements can be arranged at a distance from one another by an insulating material and/or are at least partially embedded in the material.A support material having greater mechanical rigidity than the converter elements, in particular in the force-applying or pressure-applying direction, is assigned to at least a number of piezoelectric converter elements, or the piezoelectric converter element is applied, in the form of a layer, to a supporting body made from this support material and is electrically contact-connected, for example, by a bottom electrode, which is arranged between the converter element layer and the supporting body, and a cover electrode which is applied to an outer side of the converter element layer.

摘要： A method of manufacturing a piezoelectric transducer including piezoelectric fibers in a polymer matrix is described. The piezoelectric fibers or fiber segments are jacketed with a liquid polymer substance in such a way that a distribution of longitudinal axes of the fibers or fiber segments about a preferential direction occurs. The fibers are compacted among each other and the polymer substance is cured. The resulting composite structure is subsequently so processed that areas of the fibers or fiber segments are exposed along the preferential direction. Then electrical contacts are applied on at least one part of the exposed areas. The method permits the very simple and low-cost manufacture of electro-mechanical transducers made of piezoelectric fibers.

摘要： An adaptive mirror that includes a substrate layer, on the first surface of which a reflecting layer and on the second surface of which at least one actuator is disposed. The substrate layer has a thickness of less than or equal to 1,000 μm and the mirror having at least one further metallization for thermal compensation, as a result of which a thermal deformation of the mirror is avoided or preadjusted such that the desired curvature is set as a function of the reflected power.

摘要： A pressure sensor has a multiplicity of piezoelectric converter elements which are arranged such that they are essentially parallel to a force-applying or pressure-applying direction. These can be in the form of fibres, small rods, plates or the like, and may also be in the form of a thick or thin layer. When the converter elements are in the form of fibres, small rods or plates, they are arranged at a distance from one another by means of an insulating material and/or are at least partially embedded in said material.In order to improve such a pressure sensor to the effect that it can also be used for high pressures, for a long service life and for different mechanical applications, a support material having greater mechanical rigidity than the converter elements, in particular in the force-applying or pressure-applying direction, is assigned to at least a number of piezoelectric converter elements, or the piezoelectric converter element is applied, in the form of a layer, to a supporting body made from this support material and is electrically contact-connected, for example, by means of a bottom electrode, which is arranged between the converter element layer and the supporting body, and a cover electrode which is applied to an outer side of the converter element layer.
