Cusp-singularity-enhanced Coriolis effect for sensitive chip-scale gyroscopes

Main Gyroscopes, essential sensors for measuring rotations in free space without the need for external references, play a key role in navigation and stabilization of all kinds of platforms.

Cusp-singularity-enhanced Coriolis effect for sensitive chip-scale gyroscopes. Main Gyroscopes, essential sensors for measuring rotations in free space without the need for external references, play a key role in navigation and stabilization of all kinds of platforms. The most widely used type of gyroscopes operates on the same principle that governs the flight control of certain biological organisms —the Coriolis effect, which refers to the perceived deflection of a moving object in a rotating reference frame. Known as CVGs, they sense angular rotation through Coriolis-force-induced interactions between mechanical (phononic) vibratory modes. Traditional CVGs, such as the hemispherical resonator gyroscopes (HRGs), offer high performance and reliability for applications such as oil drilling, maritime navigation and spacecraft pointing.
