Abstract

An electrically actuated control and positioning element formed of a lamella packet as a piezoelectric transducer whose ends are designed to form a power transmission element, and which is capable of transmitting tensile forces. Lamellae spaced from one another engage with parts of the power transmission element, preferably in a dovetailing or interlocking manner. Further active lamellae may be situated in the spaces between the spaced lamellae.
