In this paper, the dynamics of a dual-axis MEMS gyroscope are examined. The model for the device is based on a non-linear rod theory developed by A. E. Green, P. M. Naghdi and several co-workers. A preliminary analysis of the model, which presumes certam symmetries and small deformations, is used to examine three particular modes of operation of the device. These modes are the sensor's drive mode, tilt mode, and bomce mode. Such an analysis is a necessary precursor to the more difficult task of analyzing the effects of design imperfections on the dynamics of this device.
