Abstract

In this paper, low-frequency 32-element lineararray ultrasonic transducers were designed and fabricated using both ternary Pb(In 1/2 Nb 1/2 )-Pb(Mg 1/3 Nb 2/3 )-PbTiO 3 (PIN-PMN-PT) and binary Pb(Mg 1/3 Nb 2/3 )-PbTiO 3 (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 high-temperature ultrasonic transducer applications is promising.
