This　paper　reported　the　design,　simulation,　fabrication　and　performance　test　of　fluidic　gyroscope,　which　is　fabricated　by　using　the　integration　process　of　MEMS　process　of　silicon　wafer　and　high-precision　laser　cutting　and　modeling　process　on　PMMA.　The　3D　transient　numerical　analysis　based　on　the　fluid-structure　interaction　was　used　to　calculate　the　flow　movement.　Calculations　and　results　indicate　that　sensitivity　SFz　is　2.0　mu　V/degrees/s,　the　nonlinearity　is　less　than　0.5%.　Open　flow　channel　includes　two　inlets　and　one　outlet　inside　the　sensitive　component.　With　the　driving　of　piezoelectric　pump,　the　fluid　flows　into　the　channel　through　two　inlets　and　gathers　together.　The　flow　from　the　nozzle　forms　the　sensitive　jet,　without　a　circulation　flow　inside　the　sensitive　component.　The　sensitive　component　structure　is　simple.　Sensitive　jet　is　deflected　along　Z-axis　by　the　Coriolis　force,　the　flow　exchanges　heat　with　hotwires.　Therefore,　Wheatstone　bridge　outputs　an　unbalanced　voltage　proportional　to　angular　velocity.
