IOS Press Analysis of a ceramic bimorph piezoelectric gyroscope

Abstract. The mechanism of piezoelectric transformers for producing high voltage is incorporated into a ceramic beam bimorph piezoelectric gyroscope for generating high voltage sensing signal. For the analysis of the gyroscope, one-dimensional equations of beam piezoelectric bimorphs are derived from the three-dimensional equations of linear piezoelectricity. The equations are employed in the analysis of the bimorph gyroscope. Free and forced vibration solutions are obtained showing high voltage sensitivity. 1
