Abstract
Disclosed is a sensor device (1) comprising a piezoelectric transducer (3) and a base member (2). The piezoelectric transducer comprises a piezoelectric member with at least one excitation electrode (37, 38) connected to a first face thereof and having a thickness (h) between the first face and a second face. The piezoelectric transducer (3) is attached to a supporting face of the base member (2) with the second face of the piezoelectric transducer adjacent the supporting face of the base member. The base member comprises at least one acoustic wave reflecting tag (21) distant from the piezo-electric member.
