The invention relates to a method of adjusting, in the course of applying predetermined voltages, an oblong piezo-electric bending element which at a first end has been supported by a part protruding in the longitudinal direction of the element, whereby this part is mechanically bent and consists of a material in which at least part of the bending deformation is permanent. In addition, the invention comprises a piezo-electric bending element as has been constructed by applying the method and tools for the application of the method.
