A new type of 1-3 piezocomposite has been developed recently for advanced transducer applications. The composite made of piezoelectric ceramic tubes embedded in a polymer matrix has many unique features, such as tunability on acoustic impedance and piezoelectric response. The stress analysis indicates that the elastic parameters of polymer matrix have significant effects on the performance of 1-3 tubular piezocomposites. By optimizing the structure of composite and the elastic properties of the polymer matrix, the piezocomposite has a exceptionally large hydrostatic response, d{sub h}, and a very high receiving sensitivity. A low electric impedance and large effective piezoelectric constants suggest that the transducers in the form of the 1-3 tubular piezocomposites are superior to normal 1-3 rod piezocomposites in hydrostatic applications.
