MEMS Gyroscopes
MEMS gyroscopes, also known MEMS angular rate sensors, are small sensors used to measure angular velocity. The measurement is in RPS (revolutions per second) or degrees per second. Micro-electromechanical systems gyroscopes use the Foucault pendulum concept, which was created to provide proof of the Earth’s rotation. These small sensors use a vibrating element to determine the rotation rate.
These sensors measure an object’s rotation rate around a specific axis: single axis, dual axis, and 3-axis. They combine Coriolis force and mechanical oscillation, with the Coriolis acting as the inertial force. Inside these sensors, a capacitive block swings at predetermined rate in an opposite phase from another block. While the device rotates, the Coriolis moves the blocks slightly to the opposite direction.

Packaged in the same way as other integrated circuits, MEMS gyroscopes produce digital or analog outputs. They were first introduced for use in military operations, but they have since been adapted for commercial use.
MEMS gyroscopes are used for a variety of applications and industries. These include the following:
- Inertial measurement units (IMUs)
- Nobile applications
- VR gaming applications
- Factories and assembly plants
- Smartphones, tablets, and other portable consumer electronics
- Game controllers
- Smart homes
- Autonomous cars / self-driving vehicles
- Optical image stabilization (for use in DSLR and smartphone cameras)
They are also used in medical and defense applications.
Pros and Cons
MEMS gyroscopes has several advantages and disadvantages:
- The Pros: These sensors’ form factor is significantly smaller compared to other gyroscopes. They consume less power. They’re also ideal for mass marketing because of their affordable cost. MEMS gyroscopes are capable of integrating with a digital interface, creating a cost-efficient package.
- The Cons: MEMS gyroscopes often produce different performances across units and lots. They are prone to stress, humidity, and temperature instability. MEMS gyroscopes also produce RLG (ring laser gyroscopes) or FOG-related integration errors.
