What is the sensitivity of a single-axis gyroscope?

The sensitivity of a single-axis gyroscope refers to the proportional relationship between its output signal and the input angular velocity, that is, the change in output voltage or current caused by a unit change in angular velocity. It is an important parameter that measures the sensitivity of a single-axis gyroscope to changes in angular velocity.

Generally speaking, the higher the sensitivity of a single-axis gyroscope, the more sensitive its response to changes in angular velocity, and the greater the amplitude of the output signal. Therefore, high-sensitivity single-axis gyroscopes are more suitable for measuring smaller angular velocity changes.

The sensitivity of a single-axis gyroscope is affected by many factors, such as structural design, material selection, manufacturing process, etc. In order to improve the sensitivity of a single-axis gyroscope, the following measures can be taken:

Optimize structural design: Reasonably design the structure of a single-axis gyroscope to have higher angular momentum and smaller damping, thereby increasing its sensitivity to changes in angular velocity.

Select high-performance materials: Selecting high-performance materials, such as metal materials with high conductivity and low thermal expansion coefficient and semiconductor materials with low noise and low drift, can improve the sensitivity and stability of single-axis gyroscopes.

Improved manufacturing processes: The use of advanced manufacturing processes, such as micromachining technology, thin film technology, etc., can improve the accuracy and consistency of single-axis gyroscopes, thereby increasing their sensitivity.

Introducing compensation technology: Using technologies such as temperature compensation and vibration compensation, the error of the single-axis gyroscope can be reduced, thereby improving its sensitivity.

Adopt advanced signal processing technology: Using advanced signal processing technology, such as digital filtering, correlation detection, etc., can improve the signal-to-noise ratio of the single-axis gyroscope, thereby improving its sensitivity.

In short, the sensitivity of a single-axis gyroscope is one of its important performance parameters, and various measures can be taken to improve the sensitivity. By continuously optimizing design, selecting high-performance materials, improving manufacturing processes, introducing compensation technology, and adopting advanced signal processing technology, highly sensitive single-axis gyroscopes can be produced to meet the needs of various application scenarios.
