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.
