Abstract :
Equations for linear piezoelectricity are formulated in a reference frame rotating at a constant angular velocity and are simplified by a perturbation procedure when the angular velocity of the reference frame is small. For a rectangular ceramic piezoelectric gyroscope operating with thickness shear modes, approximate analytical solutions to the equations resulting from the perturbation procedure are obtained based on Mindlin´s equations for a piezoelectric plate
