The research of the effect of load value and dimensions of piezoelectric disk’s electrodes on its amplitude-frequency characteristics

Thanks to its unique properties piezoceramics has applications in various fields of engineering and technology. Manufacturers of piezoceramics, elements and components based on it conduct research and design work to improve the parameters of ceramics, develop its new types, for which significant financial resources are allocated. Piezoelectric disks with partial electrodes of one or two surfaces are often used to create various functional piezoelectronic devices. Disk piezoelectric devices are widely used in the elements of information systems. The purpose of this article is to research amplitude-frequency characteristics of disk piezoceramic elements, depending on the geometric dimensions of the electrodes and the load value
