  • Patent number: 11692824
    Abstract: A gyrometer including a first dual-mass gyrometer including a planar substrate, first left and right inertial masses including a first left and right frames, respectively, aligned along a first excitation axis X1 parallel to an excitation direction, and mounted with the ability to slide on the substrate along the first excitation axis X1, and first left and right central masses, respectively, mounted with the ability to slide in the first left and right frames, respectively, parallel to a first detection direction perpendicular to the excitation direction; a first coupling spring interposed between the first left and right frames; a first rocker mounted with the ability to rotate on the substrate about a first rocker pivot, first left and right ends of the first rocker being connected to the first left and right central masses, respectively; second left and right inertial masses aligned along a second axis X2 parallel to the excitation direction, and mounted with the ability to slide on the substrate along th
