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.

摘要： The invention relates to fiber-reinforced composites acting as an actuator, as a sensor and/or as a generator and to a manufacturing process. It is the object of the invention to provide such fiber-reinforced composites which can be manufactured simply and reliably and which are securely fastened and exactly positioned as elements acting as actuators, generators and/or sensors. In a fiber-reinforced composite in accordance with the invention, at least one piezoelectric element is fixed and positioned by fibers or yarn within a fiber structure or by means of fibers or yarn to a fiber structure. Flexible, electrically conductive connections which can be contacted from outside the fiber-reinforced composite are led at and/or within the fiber structure to electric connector contacts of the at least one piezoelectric element. One or more piezoelectric elements, electrically conductive connections and the fiber structure are embedded in a matrix material.
