Gyroscope sensors - how they work and what will happen in the future

Simply put, angular velocity is the amount of change in rotation angle per unit of time.

Angular velocity is usually expressed in degrees per second (degrees per second).

Gyroscopic sensor type

There are various types of gyroscope sensors. Here, different types are drawn based on size and performance.

In recent years, vibration gyroscope sensors have been applied in fields such as camera vibration detection systems for small and stationary cameras, motion sensing systems for video games, and vehicle electronic stability control (anti slip) systems.

Looking ahead, the demand for vibration gyroscopes is expected to increase in areas such as vehicle driver safety and support systems, as well as robot motion control.

Vibration gyroscope sensor

The vibrating gyroscope sensor senses angular velocity by applying a Coriolis force to the vibrating element. Due to this reason, the accuracy of measuring angular velocity varies greatly depending on the material and structure of the component. Here, we briefly describe the main types of components used for vibration gyroscope sensors.

Types of components used in vibration gyroscope sensors

Manufacturers of vibration gyroscope sensors are using various materials and structures to design compact and high-precision gyroscope sensors with excellent characteristics, including proportional coefficient, temperature frequency coefficient, compact size, seismic resistance, stability, and noise characteristics

How angular velocity sensing works (in vibration gyroscope sensors)

The vibration gyroscope sensor senses angular velocity from the Coriolis force applied to a vibrating object.

Here, we take Epson's dual T-structure crystal element as an example to explain its working principle.

Gyroscopic sensor applications

There are three main applications of gyroscope sensors.

The angular velocity generated by angular velocity sensing.

Used to measure the quantity of motion itself.

Example: Check the angular velocity generated by the sensor's own motion in the athlete's motion angle sensing perception. The angle is detected through the integration operation of the CPU.

The angle of movement is fed into the application and reflected in the application.

Car navigation system

Game controller

The cellular control mechanism perceives vibrations generated by external factors and transmits vibration data to the CPU in the form of electrical signals.

Used to correct the direction or balance of an object.

Example) Camera shake correction

Vehicle control

Examples of interesting facts in the application of angular velocity: • Car navigation system:~10 degrees/second • Vehicle control:~30 degrees/second • Camera vibration correction:~100 degrees/second • Game controller:~300 degrees/second • Sensing the swing of top golf players:~3000 degrees/second
