Figure 16.
Displacement profile of the 3-DoF micromachined vibratory gyroscope excited by a sinusoidal voltage of 0.5V amplitude and a frequency of 1.77 kHz. Due to mechanical amplification, the passive mass mf + m2 (blue) achieves a displacement of 4.07μm keeping the active mass m1 (yellow) at a displacement of 1.5 μm.
