چکیده
Abstract The effect of AC poling (ACP) on the piezoelectric and dielectric properties diced sliver-mode vibrators (L13 × W0.15–0.30 T0.51 mm 3 ) was investigated for a convex abdomen ultrasound (US) probe that is made large Pb(In 1/2 Nb )O -Pb(Mg 1/3 2/3 −0.3PbTiO (PIN-PMN-PT) single crystal (SC) plate W60 ). SC manufactured by continuous feeding Bridgman (CF-BM) method. ε 33 T / ε 0 aging rate (AR) both DCP ACP SCs were found to be within 1%/decade suggesting no obvious property degradation. After array dicing, considerable decrease in electromechanical observed. post-dicing DCP, DCP-DCP 0.15 wide slivers showed coupling factor ( k ′ 33 4300 89.1%, respectively. ACP-DCP improved 5980 92.2%, respectively, which are considered useful practical medical transducer applications.
