Abstract

The invention relates to an electromechanical drive or a sensor element composed of piezoelectric elements arranged in the form of a stack. The drive or the sensor element is intended for measurement instruments and operates even at very high temperatures.The new drive or the new sensor element (10) for this purpose comprises a number of piezoelectric ceramic layers (12a-f), with electrode layers (16a-e) in each case being arranged between two mutually facing surfaces of directly adjacent piezoelectric ceramic layers. Connectors (18a,b) in the form of wires run in grooves (14a-d) in the electrode layers (16a-e) in order to make electrical contact with the electrode layers (16a-e), and are passed out of the electrode layers (16a-e).
