Yeghiazaryan, Eduard Ludvikovich

He began his career in 1957 as a fitter-assembler of the Electrical Engineering Plant of the city of Leninakan, Armenian SSR.

In 1965 he graduated from the Engineering Department of the Moscow Higher Technical School (MVTU). N. E. Bauman , specialty "Instruments of Precision Mechanics". While still a third-year student, E. L. Yeghiazaryan began his first scientific research under the guidance of the outstanding Soviet designer of artillery weapons, professor , colonel-general of technical troops V.G. Grabin in the student design bureau he created.

In 1976 he graduated from full-time postgraduate study at the Moscow Technical University. N.E. Bauman.

He worked at the enterprises of the defense industry of the Moscow region and Moscow as an engineer, head of the design and technological team, leading designer, head of the laboratory; subsequently - the director of the Microsensor Research and Development Engineering Center organized by him.

In 1997, he was elected a corresponding member of the Russian Cosmonautics Academy named after K. E. Tsiolkovsky, in 2000 - a full member of the International Academy of Authors of Scientific Discoveries and Inventions.

Among the first in the country (1972) began work on the creation of a new generation of strain gauges - semiconductor microelectronic sensors (microsensors), as well as control , measurement and control systems based on them. These works, along with the works of other specialists, subsequently led to the formation of a new scientific and technical field, called “microsensorics” ^{[1] [2] [3]} . He has completed a number of innovative scientific and engineering developments in this area.

He developed, manufactured and implemented microsensors in various fields of science and technology (medical, microbiological , neurophysiological , airship building, underwater, etc.). So, the micro pressure sensors created by E. L. Yeghiazaryan were tested in 1978 at the Cardiology Center of the Academy of Medical Sciences of the USSR and made it possible for the first time in world practice to directly measure pressure directly in the cavities of the heart and blood vessels with a microsensor implanted into these organs ^{[1] [2 ] ]} . The apparatus developed and implemented by him at the Institute of Higher Nervous Activity and Neurophysiology of the Academy of Sciences of the USSR for studying the supporting reaction of an animal (dog) upon excitation of the corresponding sections of the nerve centers of the brain allowed specialists to carry out a number of important neurophysiological studies ^[4] .

He carried out experimental studies of stress concentration in areas with extremely small (comparable with the size of the crystal lattice ) radii of “sharp” surface transitions in the semiconductor sensitive element of the load cell. The studies made it possible, on the one hand, to develop recommendations for a significant increase in the sensitivity of microsensors, on the other hand, to establish the causes of damage in the field of stress concentrators for micro- and macrostructures, not described by the classical theory of stress concentration.

Author of studies on the physicochemical properties of materials to create structural elements of microsensors. He is the author of structural, technological, circuitry and topological methods and methods for designing microsensors for measuring parameters of linear and angular movements, pressures , flow rates of liquids and gases, deformations , mechanical stresses , etc., as well as parameters of electrical and magnetic quantities.

The designs of the devices created by him ( accelerometers , flowmeters , micro tensometers , pressure microsensors, gas and liquid meters , etc.) are protected by more than 35 copyright certificates of the USSR and RF patents ; development materials published in more than 50 articles, embodied in 25 major R&D and search research ^[5] .

For many years he conducted active organizational and popularization work in the area of ​​supporting and establishing a new scientific and technical direction, introducing microsensors and systems based on them into mass production ^{[6] [7]} .

In accordance with the rules previously in force in the Russian Federation established by the Russian Agency for Patents and Trademarks (Rospatent) , inventors were not allowed to name their inventions, which included their own name, which unlawfully restricted the rights of authors of inventions when applying for patents. E. L. Yeghiazaryan managed to achieve the adoption in 2000 by the Supreme Court of the Russian Federation of a decision recognizing this provision as invalid and repealing it ^[8] .

He was buried in Gyumri , Armenia .

In 2007, in accordance with the decision of the Administration of Gyumri, a memorial plaque was erected on the facade of the house where E. L. Yeghiazaryan spent his childhood and youth (d. 242 on Abovyan St. in Gyumri) ^[1] .
