Abstract
Lead magnesium niobate–lead titanate (PMN–PT) single crystal has ultra-high piezoelectric properties compared with conventional piezoelectric materials and is suitable for high-performance ultrasonic transducer application. In this paper, an improved process has been used for fabricating an annular array ultrasonic transducer using PMN-PT single crystal. A 35 MHz annular array with 8 elements has been built. The bandwidth of the array elements were around 45%. At the center frequency, the insertion loss ranged from −21dB to −28dB. The electrical cross-talk between the adjacent elements was in a range of −24dB to −31dB.
