DEFORMATION DETECTING ELEMENT WITH DISPERSION STRUCTURES Russian patent published in 2010 - IPC G01L1/16 G01B21/32 

FIELD: physics.

SUBSTANCE: deformation detecting element with dispersion structures consists of piezoelectric plates on whose surface there is at least one interdigital converter and at least two dispersion reflecting structures, which uses the response lag time of the deformation detecting element as an information signal. The reflecting structures are on two sides of the interdigital transducers. The information signal can also be in form of the wave form or central frequency of a frequency-modulated probing signal, which ensures maximum amplitude response value of the deformation detecting element with dispersion structures.

EFFECT: higher accuracy of measuring deformation owing to use of information on the central frequency of the device.
