CEA-Leti Reports Breakthrough High-Performance Gyroscope For Automotive, Aeronautic and Industrial Applications
World's First NEMS-Based Gyroscope Operates at 50 kHz,

GRENOBLE, France – Jan. 26, 2021 – CEA-Leti scientists, working with researchers at Politecnico di Milano, have developed the world's first high-performance gyroscope for operating in severe environments, such as industrial and aeronautic equipment and automobiles. The breakthrough proves it is possible to detect minute rotational movement even among system vibrations.
- Common in everyday objects, inertial sensors must be designed to meet ever-increasing constraints of miniaturization and cost, as well as requirements for performance and robustness. For certain automotive, industrial and military applications, gyroscopes must be able to detect a variation of one degree per hour, i.e. a speed of rotation about ten times slower than that of the earth, in environments that are subjected to strong, consistent vibrations.
- Low-power MEMS gyroscopes are used in multiple fields because of their small footprint and low power consumption. They can monitor and control device position, orientation, direction, angular motion and rotation. Their integration into automobiles improves vehicle stability through an electronic stability-control system. They also can be used for dead reckoning – the determination of a car, ship or aircraft position without the aid of celestial observations – in driverless cars. Their integration into smartphones allows detection of unit rotation and twist (gesture-recognition functions), indoor navigation when GPS is disabled and mixed reality, among other functions.
