In this paper, low-frequency 32-element lineararray ultrasonic transducers were designed and fabricated using both ternary Pb(In1/2Nb1/2)-Pb(Mg1/3Nb2/3)-PbTiO3(PIN-PMN-PT) and binary Pb(Mg1/3Nb2/3)-PbTiO3(PMNPT) single crystals. Performance of the array transducers was characterized as a function of temperature ranging from room temperature to 160°C. It was found that the array transducers fabricated using the PIN-PMN-PT single crystal were capable of satisfactory performance at 160°C, having a-6-dB bandwidth of 66% and an insertion loss of 37 dB. The results suggest that the potential of PIN-PMN-PT linear-array ultrasonic transducers for higherature ultrasonic transducer applications is promising.
