Abstract. The selective polarization technique of ferroelectrics representing sound-conductors and piezo-electric transformers in different devices of functional electronics is described. The feature of the technique is the ability of creating the local polarization regions, with different, in the magnitude and orientation, polarization vectors and with different electrophysical parameters, in the monolithic ceramic sound-conductor. The examples of specific acousto-electron units based on surface acoustic waves with the essentially improved electrical parameters, simpler construction and higher processibility are presented. The features of the selective polarization process are shown, the recommendations on the usage of the technique are given.
Keywords: ferroelectric, domain, sound conductor, polarization, converter, wave, parameter.
