Broadband piezocrystal transducer array for non-destructive evaluation imaging applications
Abstract
A 32-element, 5MHz linear array, incorporating PMN-PT 1-3 piezo-polymer composite, has been designed using finite element (FE) modelling. The Elasto-Electric material properties of the PMN-PT samples were characterized and evaluated within the FE model to ensure accurate corroboration. The array configuration and performance were then investigated, including array microstructure, and steering and focusing ability. The matching and backing material selection, array sensitivity and bandwidth were assessed using pulse echo responses. Imaging performance was then undertaken, employing full matrix capture and total focusing method. For performance comparison, a reference array comprising of conventional PZT5H ceramic was also investigated, following the same design criteria. The piezocrystal device provides a bandwidth of 87% and a sensitivity-bandwidth product improvement of 160% when compared to the reference PZT5H based array.
