Strength of multiferroic layered structures in position sensor structures

Abstract

The article is devoted to modeling and calculating the strength of multiferroic layered structures in the designs of position sensors used in various practical applications, including CPS sensors. Progress in the study of new multiferroic layered structures in which a giant magnetoelectric effect has been discovered has opened up completely new prospects for the design of position sensors. The studies carried out open up obvious prospects for creating economical and cheap sensors for use in CPS structures, as well as electric motors for determining angular positions and other automated systems. The strength test of magnetostrictive-piezoelectric two-layer structures metglas/PZT, metglas/(LiNbO3 cut Y+140°), metglas/GaAs was carried out in the bending mode of the magnetoelectric effect. It was found that in all cases the strength condition is satisfied with a very good margin. Thus, the reliability of position sensors with a magnetoelectric structure is fully ensured. The studies carried out open up obvious prospects for creating economical and cheap sensors for use in CPS structures, as well as electric motors for determining angular positions and other automated systems.
