Publication number: 20210159868Abstract: System and methods for a hollow-disk radial-contour mode resonator structure. The hollow disk reduces the dynamic mass and stiffness of the structure. Since electromechanical coupling Cx/Co goes as the reciprocal of mass and stiffness, the hollow disk structure has a considerably stronger electromechanical coupling than a solid one at the same frequency, and thus raises Cx/Co without excessive gap-scaling. Several embodiments of hollow disk resonators are detailed, including asymmetric and symmetric disk configurations.Type: ApplicationFiled: November 13, 2020Publication date: May 27, 2021Applicant: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Clark T.-C.
