More Information
Summary:The invention relates to an gyroscopic sensor (2) comprising: - a sensitive element (4) designed to vibrate; - an electrode carrier (8) capable of carrying excitation/detection electrodes (20) for exciting the sensitive element (4) and for detecting the vibration of the sensitive element (4); and - elements (10, 16) for supporting the electrode carrier (8); characterized in that the supporting elements (10, 16) comprise a base (10) made of a material having a density of less than 5 kg/dm3, and the square root of the ratio of Young's modulus divided by said density is greater than 9 GPa1/2.dm3/2/kg-1/2.
