The piezoelectric element is one of the most popular electronic components in use, which are used as part of many electronic devices. These devices are very effectively used in medicine, education, construction, oil and gas industry, military equipment, metrology and many others. They are part of devices that provide diagnostics of various human organs, measurement of the flow of pumped liquids and gases that utilize mechanical energy of a person and vehicles for the purpose of its subsequent conversion into electrical energy. In order to obtain a piezoelectric effect, it is necessary to indicate certain effects on the crystal. Such effects include: application of excessive pressure; compression; stretching; torsion. The criteria that affect the effectiveness of multilayer piezoelectric converters are discussed below.
