On November 2, 2018, the presentation and cancellation of three new postage stamps, which are being put into circulation to pay for postal services in Ukraine, took place. These stamps are dedicated to inventions that have made Ukraine famous all over the world. One of the brands is dedicated to the invention of a fundamentally new engine – a piezoelectric engine, the author of which is a senior researcher Viacheslav Vasylovych Lavrinenko. The invention relates to 1964. At that time, a young specialist V.V. Lavrinenko at the Department of Dielectrics and Semiconductors (now the Department of Microelectronics) conducted a study of the power piezoelectric transformer and found its rotation in the holder. Having deeply studied the physics of this phenomenon, V.V. Lavrinenko created the world’s first piezoelectric motor of rotation, and later a linear motor to drive a relay. Viacheslav Vasylovych’s work was decades ahead of similar work abroad. Subsequently, V.V. Lavrinenko developed all the basic principles of operation and design of piezoelectric motors. More than 200 copyright certificates and patents have been obtained for the invention of the piezoelectric motor, about 40 of which are patents in foreign countries.
Given the prospects for the use of piezoelectric motors at the Department of Microelectronics, a branch laboratory of piezoelectric motors was created, headed by V.V. Lavrinenko. The developments of this laboratory are embodied in the serial production of motors for the VCR “Electronics-532”, for the slide projector “Dnepr-2”, for film cameras, drives of vending machines, ball valves, etc. Millions of piezoelectric motors are now being mass-produced in various countries around the world.
The invention of the piezoelectric motor is one of the world’s greatest inventions. Unfortunately, there are currently no companies in our country that mass-produce piezoelectric motors. Today V.V. Lavrinenko continues to work on the improvement of piezoelectric motors in a very modest position as an engineer of the Department of Microelectronics.
