Optimization and characterizations of the dual axis gas gyroscope

This paper presents the optimization of the sensing element and characterizations of the dual axis gas gyroscope. Six different design of the sensing element were simulated to obtain higher sensitivity with lower power consumption. The influence of the arms structure to the thermal distribution along the thermistor was clarified. The working principle and the cross-sensitivity of the gas gyroscope are also analyzed. Experiments were performed to confirm the simulation results and good agreement has been realized. The sensor is expected to be applied in ship anti-rolling and stabilization systems
