(EN) COMPACT HIGH-PERFORMANCE RESONANT MICROMECHANICAL GYROMETER
(FR) GYROMETRE MICROMECANIQUE RESONANT PERFORMANT A ENCOMBREMENT REDUIT
Abstract
(EN)
Disclosed is a resonant micromechanical gyrometer comprising a support (2) and a movable mass (4) that can vibrate relative to the support (2) in a gyrometer plane, excitation means (8) for exciting the movable mass (4) in a first direction (X), and detection means (10) for detecting the vibration of the movable mass (4) in a second direction (Y), characterized in that the gyrometer comprises at least one leg (6) that is anchored to the support (2) at a first end and is fastened to the movable mass (4) at a second end and allows the movable mass (4) to vibrate along the first (X) and second (Y) directions in the gyrometer plane.
