A microscopic sensor for measuring angular velocity.

Microgyroscopes are expected to be applied as microrobot attitude sensors. Rotational and vibrational gyroscopes are based on the Coriolis force. Ring laser gyroscopes and optical fibre gyroscopes are based on the Sagnac effect. Among these types of gyroscope, vibrational gyroscopes (the tuning fork- and resonant piece-types) are suitable for miniaturization and are being developed for miniaturized applications.
