Abstract:
A microgyroscope comprising:an inner frame as an inner mass part excitedly installed within an outer frame to be unitizingly excited together;a first plurality of combs installed laterally and in a y axis direction at both sides of said inner frame and within said inner frame;perpendicular direction sensing electrodes disposed between the first plurality of said combs at certain intervals, and supported by electrode supporting parts;outer mass parts installed at both sides of said inner mass part;elastic bodies excitedly installed between said outer frame and said outer mass parts;oscillation structures extending in a lateral direction of said outer mass parts;a second plurality of combs installed at a side of each of said oscillation structures;exciting drivers for causing excitations by supplying a voltage; anda third plurality of combs disposed respectively between the second plurality of said combs of said oscillation structures, for detecting the excitations from a difference of capacitances between said exciting drivers.
