Abstract:
Disclosed is a piezoelectric transducer of the type including a stack of a contact piece, a piezoelectric pellet and a support of very great stiffness. Specifically, the contact piece forms tips, the respective apex of which constitutes contact points that are spatially isolated from one another. Also disclosed is a process for the manufacture of such a contact piece as well as a resonant ultrasound spectroscopy device including one or more of such piezoelectric transducers.
