Modification and practical application of piezoelectric transducers with separated electrodes

The paper presents the results of improving the technology of forming current-conducting electrodes of piezoelectric elements and the development of devices from piezoelectric ceramics with separated electrodes by a method based on the technology of combined electron-beam modification. The prospect of using the method of thermal vacuum deposition for obtaining electrode coatings on products made of piezoelectric ceramics of the PZT grade is shown. It has been found that silver coatings formed by the proposed technology on piezoelectric elements are more uniform and homogeneous in comparison with the coatings obtained by the traditional (industrial) method. As a practical result of the implementation of the technology proposed in the article, designs of piezoelectronic devices based on elements made of piezoelectric ceramics with separated electrodes formed on their surface, in particular, a multisectional piezoelectric transducer, have been developed. Changing the size of the electrodes, their relative position allows to influence the parameters of the output signals and opens wide opportunities for the design of piezoelectric transducers of computer systems for critical applications. The main advantage of using transducers made from piezoceramic materials in computer systems is due to their special structure, which allows to implement fundamentally different schemes in one such element
