Abstract
Disclosed is a method and device for electrically activating an electromechanical element () for positioning an element to be driven which is in contact at least intermittently with the electromechanical element (). By temporal sequence or by the successive execution of a static friction phase and a slip phase, the element to be driven performs a discrete drive step in a first drive direction, while by temporal sequence or successive execution of a slip phase and a static friction phase the element to be driven performs a discrete drive step in a second drive direction which is oriented contrary to the first drive direction. By appropriate repetition, a plurality of discrete drive steps and thus a large travel can be realized, which is limited in principle only by the extent or length of the element to be driven.
