Abstract :
The performance of 128channel 7.5 MHz linear array ultrasonic probe using 0.67Pb(Mg13/ Nb23/)O3-0.33PbTiO3 single crystal was investigated. The fabrication process was modified as the mechanical and electrical properties difference between PMN-PT single crystal and conventional PZT. The sensitivity of the PMN-PT single crystal probe is about 3 dB higher than that of the conventional PZT probe, and the -6 dB bandwidth is about 30 % broader. The sensitivity variation of PMN-PT probe was similar with PZT probe.
