Towards Inertial Grade Vibratory Microgyros: a High-q In-plane Silicon-on-insulator Tuning Fork Device
Year: 2004
Type: conference-paper
Abstract: This paper reports on the design and implementation of an in-plane solid-mass single-crystal silicon tuning fork gyro that has potential to achieve inertial-grade performance.A novel design is devised to achieve high Q in the drive and sense resonant modes (Q drive =84,000 and Q sense =64,000) with effective decoupling.The gyroscope was fabricated on 40µm SOI using a two-mask process.The drive and sense resonant modes were matched electronically to within 0.07% of each other and the measured rate results show a sensitivity of 1.25mV/º/s in a bandwidth of 12Hz.
