Abstract (en)
The device has a flat piezoelement (6) with upper and lower sides on which electrode structures (5,7) are arranged, each connected to a connection electrode (1,4). At least the underside of the piezoelement including the electrode structure interacts with a coupling medium (11) with an exposed surface facing away from the piezoelement and via which ultrasonic waves can be coupled directly into the medium or detected from the medium.
