Abstract: This talk explores the ability of the micro vibrator providing both high-g vibration and high angular rate rotation. The equations analyzed indicate that higher vibration frequency and driven voltage, thinner PZT and silicon film and reduced equivalent mass of the moving platform can increase the peak acceleration. A simple experiment using commercial MEMS accelerometer AD22281 mounted on a z-axis vibrator is designed to demonstrate the feasibility of prognostic both high-g and angular rate characteristics of generic MEMS inertial sensors with micro vibrator. Finally, a general prognostic scheme for generic MEMS inertial sensors’ health status is developed.
