Abstract

Es wird ein Piezoaktor (2) mit einem Piezoelement (3) vorgeschlagen, bestehend aus einem Mehrschichtaufbau von Piezolagen, wobei zwischen den Piezolagen angeordnete Innenelektroden in Richtung des Lagenaufbaus des Piezoelements (3) abwechselnd mit einer unterschiedlichen Polarität einer elektrischen Spannung beaufschlagt sind und mit einem mindestens die Piezolagen umgebenden in vorgegebenen Grenzen elastischen Isolationsmedium (10). Das Piezoelement (3) ist von einer elastischen Kunststoffumspritzung (10) als Isolationsmedium umgeben und der Piezoaktor (2) weist einen Aktorfuß (4) und einen Aktorkopf (5) auf, die jeweils mit der Kunststoffumspritzung (10) mechanisch verbunden sind, wobei die Verbindung zwischen der Kunststoffumspritzung (10) und mindestens mit dem Aktorkopf (5) über eine Verkrallung (11) der aneinander liegenden Oberflächen gebildet ist.
