篗icromachined gyroscope is a new kind of devices in navigatio applications. However，most of them are vibratory gyroscopes because of its simple fabricating processes．In thispaper，a new configuration of micromachined gyroscope based on an open-loop，stable electrostaticsuspension disc is described．The input angular velocity axis of this gyroscope could be in any radialdirection of the disc．Its basic principle is given in this paper．The raw experimental result is alsopresented．
