MICRO-ACOUSTIC-ELECTROMECHANICAL GYROSCOPE AND OPERATION METHOD THEREOF Russian patent published in 2010 - IPC G01C19/56 G01P9/04 

FIELD: physics.

SUBSTANCE: gyroscope has two identical plates 1 and 1¹ of a piezoelectric, on one side of which there are regular structures of inertial masses in nodes of a standing surface acoustic wave (SAW) which is generated in on direction by active interdigital transducers (AIT) with reflecting structures and perpendicular measuring interdigital transducers of the resultant field of the SAW of regular structures of inertial masses, consisting of diffraction and signal SAW fields from Coriolis force.

EFFECT: low level of the noise signal on measuring interdigital transducers without rotation of the object, higher level of useful signal on the said interdigital transducers when the gyroscope rotates about the axis 10.
