Abstract

The electrostatic negative-stiffness behavior of vertical structures under out-of-plane motion decreases the resonant frequency and deteriorates the linearity of a lateral-axis tuning-fork gyroscope (TFG). An electrostatically isolated silicon island is proposed to suppress this behavior. The negative-stiffness behavior is observed and the effectiveness of the electrostatic isolation is experimentally verified. The nonlinearity of the TFG is reduced to 0.34% with a full range of 1,000°/s. This is a 5• improvement.
