PZT-Polymer Elements for Advanced Sonar Transducers

PZT polymer composite (Piezocomposite elements and linear arrays for advanced sonar transducers developed by NMRL as a high promise alternative for conventionally used PZT piezoceramic material having the limitation like high acoustic impedance, higher weight factor and poor mechanical properties. The Piezocomposite based sonar transducers exhibit enhanced receiving and transmitting response over a large frequency bandwidth and narrow beam width
