description 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.
