Newnham and L.E. Cross in the late 1970's . A variety of piezo composite materials can be made by combining piezo ceramic elements with a passive polymer such as epoxy or active polymer. Piezo composites are classified according to their connectivity (such as 2-2, 1-3, 0-3 etc.,). Connectivity is defined as the number of dimensions through which the material is continuous. It is conventional for the first digit to refer to the piezoelectrically active phase.1-3 piezo composites advantages over standard bulk piezo ceramics are in general: lower acoustic impedances, from 8MRayl to 26MRaylhigh coupling coefficients of typically 0.61 to 0.75high bandwidth and lower QmProduct Parameter:Piezoelectric ceramic fiber composite 2.5Mhz 19x20ZminZmaxFree capacitanceQmKtKpDielectric constantFsFpd332.4Ω987Ω2.39nF370.6550.774402ε2.503.11280Application:Medical Diagnostic UltrasoundNon-Destructive Testing (NDT)SONAR, underwater high performance applicationsFlow Control and Air Ultrasound
