Gyroscopes are also available in different sizes with different performances.īased on their sizes, Gyroscope sensors are divided as small and large-sized. More accurate measurements of orientation and movement in a 3D space became possible with the integration of the Gyroscope sensor. With the advance in technology highly accurate, reliable and miniature devices are being manufactured. This change is used to measure the external rotational force applied to the sensor as Angular rotation. These vibrations caused in the sensing arm are measured as a change in electrical charge. Rotation of the stationary part leads to the vertical vibrations in sensing arms. This leads to the vibration of the Drive arms in the upward and downward directions due to which a rotational force acts on the stationary part in the center. When the external rotational force is applied to the sensor vertical vibrations are caused on Drive arms. This keeps the stationary part at the center and sensing arm remains static.

As Drive arms are symmetrical, when one arm moves to left the other moves to the right, thus canceling out the leaking vibrations. When an alternating vibration electrical field is applied to the drive arms, continuous lateral vibrations are produced. This structure comprises a stationary part in the center with ‘Sensing Arm’ attached to it and ‘Drive Arm’ on both sides.
