Abstract

Es wird ein Piezoaktor vorgeschlagen, bei dem mindestens ein Piezoelement (2; 21; 31; 41, 42) zur Beaufschlagung eines Betätigungselements mit einer Zug- oder Druckkraft vorhanden ist. Es sind weiterhin Stabilisierungselemente vorzugsweise aus Stahl oder Keramik (9; 22) angeordnet, die parallel zum Piezoelement (2; 21; 31; 41, 42) mit einer zwischen den Elementen liegenden flexiblen Zwischenschicht (11) aus Kunstsoff angebracht sind, welche Bewgungen quer zur Nutzrichtung verhindern. Das Piezoelement (2; 21; 31; 41, 42) und die Stabilisierungselemente (9; 22) weisen dabei eine in Wirkrichtung (z-Achse) große Länge im Verhältnis zu ihrer Breite quer zur Wirkrichtung (x, y-Richtung) auf.
