摘要： The invention relates to an inertial sensor (2) able to measure information relating to rotation in 3 orthogonal axes, comprising a support and a vibrating sensitive element (6) secured to the support; said sensitive element (6) having a deformable frame (10) which extends in a plane (X-Y) and at least two deformable projections (13, 14; 15, 16) which extend in the same plane (X-Y); characterized in that the inertial sensor extends in one and the same plane; the deformable frame (10) and said at least two deformable projections (13, 14; 15, 16) have a plane of symmetry parallel to the plane (X-Y); said at least two projections are rectilinear beams which have an approximately square cross section, are not collinear and are preferably approximately orthogonal to one another; each of said deformable beams (13, 14; 15, 16) being connected only by one of their ends to the deformable frame (10) at a location at which the amplitude of the primary vibration mode is at a maximum; and in that said sensor has a device for detecting each of the secondary vibration modes.
