Piezoelectric Cylindrical Vibrating Gyroscope

In recent years, automatic driving has been attracting attention, and the miniaturization of gyros, which are important for realizing such automatic operation, is expected to increase. MEMS piezoelectric vibration gyros, which are compact, low-cost, and high-performance, have attracted much attention. In our previous research, we developed a disk-type gyro using lithium niobate, which is expected to have high performance. However, the drive frequency is high, and there exists a limit to miniaturization. Therefore, in this study, we designed a cylindrical gyro whose drive frequency can be reduced.
