| Abstract [eng] |
A novel measurement technique for simultaneous monitoring of the piezoelectric properties and structural changes of the PMN-32%PT single crystal during poling process has been proposed and successfully implemented. Numerical and experimental analysis of vibrations of piezoelectric PMN–32%PT crystals in steady-state and transient modes. Ultrasonic air-coupled transducers and phased arrays operating in a low frequencies range were developed and investigated both in the transmitting and receiving modes. Selection of the appropriate vibrations modes and optimization of the geometry of PMN-32%PT crystals for air-coupled ultrasonic transducers and arrays. |
