Abstract
A sensor device contains at least one sensor chip having at least one MEMS structure arranged at a main surface of the at least one sensor chip, wherein the at least one sensor chip is configured to transmit ultrasonic signals and/or to receive ultrasonic signals. The sensor device further contains an acoustic coupling medium arranged selectively on the at least one MEMS structure, wherein the acoustic coupling medium is configured to decouple an ultrasonic signal to be emitted from the at least one MEMS structure and/or to inject a received ultrasonic signal into the at least one MEMS structure. The acoustic coupling medium only partially covers the main surface of the at least one sensor chip.
