• For obtaining greater accuracy and stability of piezoelectric gyroscopes, the authors have advanced the research on H-type LiTaO3 single-crystal piezoelectric gyroscopes, which combine the tuning fork vibration with H-type vibration. In this paper, the H-type LiNbO3 gyroscope of an oppositely polarized single crystal plate is reported. The electromechanical coupling factor of LiNbO3 is larger than that of LiTaO3 for the flexural vibration mode. Using an oppositely polarized plate, the electrode construction without a side electrode becomes possible. Therefore, the possibility of miniaturizing the H-type single-crystal piezoelectric gyroscope is examined to obtain the same sensitivity level. In the trial experiment, the dimensions of the LiNbO3 gyroscope were reduced to be 1/8 that of the LiTaO3 gyroscope.
