  • Two typical applications of PMN-PT crystals are medical ultrasound and non-destructive testing (NDT). The superior coupling coefficient and electro-mechanical properties give PMN-PT crystal several advantages:

    1) Very high sensitivity
    2) Very broad bandwidth

    These advantages would translate into high imaging quality and efficiency.

    Domain engineering is an important part of crystal application, Innovia uses its expertise in selecting the most suitable crystal boule, cut direction and poling direction in order to optimize piezoelectric properties. For instance, when high d33 and k33 are desired, Innovia uses crystal boules grown along [001], cuts (001) plates out of the boule and poles along [001] so product performance is maximized and in-plate property variation is minimized. Below is a set of recommended domain engineering factors for each applications.
