At this point in manufacturing, the ceramic pieces are not yet piezoelectric devices. The sintered PZT chips are isotropic and must undergo poling in order to function as a piezoelectric device. Poling subjects each device to a strong electrical field across the electrodes (Figure 7), which then activates the ceramic's piezoelectric properties.
