Abstract :
Dual layer piezoelectric transducer has been developed using an adhesive free process and characterized both experimentally and by FEM models. Our findings show an enhanced amplitude when both layers are used as a transceiver system for sufficiently large pulse width. The peak frequency obtained from Comsol modeling shows a good agreement with the experimental results.
