Study and optimization of screen-printed PZT transducers for acoustic applications

In this paper, we present the manufacture and characterization of a screen-printed, acoustic PZT component with enhancement of its properties by optimizing the poling and densification process. We discuss results obtained on ferroelectric properties using remnant hysteresis cycle measurements, piezoelectric properties by evaluation of the d
₃₃
coefficients and electrical properties by measuring the capacitance. In addition, the first acoustic characterization by spectrum analysis is presented.
