This paper reports the design and analysis of a novel micro thermo-fluidic gyroscope utilizing dual directional liquids. Compared with the traditional jet deflection method, the proposed gyroscope comprises two pairs of symmetric microchannels splitting from the main channel. When the Coriolis force induced by external rotation acts on the fluid, the mass flow rate of the symmetric microchannels will be unequal, which results in different thermal convections between the fluid and thermistors inside the split microchannels. Through measuring the temperature difference between the symmetric thermistors, the angular rate is obtained. The gyroscope is applicable for both even and uneven angular rate condition. Numerical simulation is applied to investigate the gyroscope performance, which concludes that the mass flow rate difference between the symmetric microchannels and the temperature difference between the symmetric thermistors show good linearity to the angular rate, the nonlinearity are 0.099% and 0.15% respectively.
