Abstract:
This paper introduces a practical design and fabrication of a small hydrophone which combines the structure of cymbal-type transducer with the material of PMN-0.33PT. Finite element method (FEM) is used for the receiving sensitivity analysis. Compared with PZT-5A, PMN-0.33PT shows higher receiving voltage sensitivity in various designs of the cymbal transducers.
