Abstract
An angular velocity sensor structure for improving the off-axis sensitivity is provided in which a structure for detecting an off-axis acceleration component applied to the angular velocity sensor structure is directly adapted to the sensor structure, thereby measuring the off-axis acceleration component actually applied to the sensor structure without distortion.
Claims4
An angular velocity sensor structure comprising:
- a driving unit movably formed on a board;
- an angular velocity detecting unit formed on the board that detects angular velocity by the motion of the driving unit;
- and
- an off-axis acceleration detecting unit formed on the same board as the angular velocity detecting unit that detects off-axis acceleration by the motion of the driving unit
- wherein the angular velocity detected by the angular velocity detecting unit is corrected using the off-axis acceleration detected by the off-axis acceleration detecting unit.
