US Patent 9303995 Gyroscopic sensor

The invention relates to an gyroscopic sensor comprising a sensitive element designed to vibrate; an electrode carrier capable of carrying excitation/detection electrodes for exciting the sensitive element and for detecting the vibration of the sensitive element; and elements for supporting the electrode carrier. The supporting elements comprise a base 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.
