Monolithic piezoelectric transducers [PDF]
The Journal of the Acoustical Society of America, 1989 This paper will review new piezoelectric transducers concepts where layers of lead zirconate titanite (PZT) have been electroded and then cofired into a monolithic structure that was ready for poling and use in various types of transducers. These techniques were initially developed for underwater military applications, but are now ready to be applied ...
