Title: Vibrations rejection in gyroscopes based on piezoresistive nanogauges
Abstract: The work discusses the effects of vibrations on the performance of rate gyroscopes in terms of Allan variance, and presents the results of vibrations rejection on a Z-axis gyroscope based on piezoresistive nano-gauge sensing elements. In a comparative analysis with a consumer off-the-shelf gyroscope, the proposed device shows a 10-fold better angle random walk (ARW) under no vibrations, and at least a 100-fold better Allan variance, when acquired under vibration amplitude of ±6 g (gravity units), at frequencies up to 10 kHz.
