This paper reports the development of micro rate gyroscope using electro-conjugate fluid (ECF). ECF is a kind of dielectric fluid, which produces powerful flow (ECF-jet) by applying high DC voltage between electrodes inserted in the fluid. By applying this ECF-jet to a novel gyroscope driving principle, gyroscope whose principle is similar to a gas rate sensor which operates by Coriolis force can be realized. In this study, we studied and optimized principal parameters of ECF micro rate gyroscope in order to lower the driving voltage and to make volume smaller. We realized that by choosing a suitable parameter, the angular rate was able to be detected at an applied voltage 0.4kV, and the lowering the voltage was achieved. In addition, the range of detection is more than 400°/s was obtained.
