piezoelectric sensor library for proteus

              In order to play a role in the application of hydrophones, piezoelectric composites of piezoelectric tubes transducer are gradually developed in the 1970s. 

             Piezoelectric composites consist of piezo ceramics and polymer phases that are constructed in accordance with a certain connection method of piezo transducer circuit . 

                Electrical effect of functional composite materials. Due to the addition of flexible polymer phase, the density, acoustic impedance, and dielectric constant of piezoelectric composites are reduced, while the composite material's merit and electromechanical coupling coefficient are improved, it is overcoming the simple pressure. 

              It is the drawbacks of the piezo ceramics and the high cost of piezoelectric sensor price . Piezoelectric composites are used not only as piezo tube stack for hydrophones, but also in the industrial, medical, and telecommunication fields. 

             After more than 40 years of continuous research, piezoelectric composites have Its applied research has made considerable progress, but piezoelectric ceramic vibration sensor complete theory has not yet been established, and its application and development have yet to be fully tapped. 

             Currently, the research of piezoelectric composite materials mainly focuses on the development of connection types, piezoelectric hemisphere cap is the improvement of molding processes and the preparation of multi-functions.
