Stmicroelectronics Drives Highprecision MEMS Gyroscope Innovation

As technology continues its rapid evolution, intelligent devices are becoming increasingly sophisticated and responsive. From drones navigating complex airspace to robots executing precise maneuvers and wearables tracking human movement, these applications all rely on a critical sensor component: the gyroscope.

STMicroelectronics, a leader in microelectromechanical systems (MEMS) technology, has developed a portfolio of high-performance gyroscopes that form the foundation for motion sensing applications across multiple industries.

Modern gyroscopes measure angular velocity around three perpendicular axes (X, Y, and Z), essentially providing devices with spatial awareness comparable to human balance and orientation senses.

MEMS gyroscopes operate on the Coriolis effect principle. When a vibrating structure within the gyroscope experiences rotation, the resulting Coriolis force generates measurable signals that precisely calculate angular velocity.

The integration of gyroscopes with accelerometers creates inertial measurement units (IMUs) that provide comprehensive motion tracking by combining rotational and linear movement data. These IMUs have become essential components in applications ranging from aerial drones to virtual reality systems.
