Embodiments relate to an IMU sensor and an inertial measurement system comprising same, wherein the IMU sensor comprises: a core body including at least three surfaces each having a surface direction parallel to any one of three axes; a plurality of cantilevers configured to be deformable, one side of each cantilever being coupled to the core body; and a plurality of strain sensors each disposed on the surface of each cantilever, the strain sensors extending along the direction of the other side from one fixed side of the cantilever.

Embodiments relate to a torsion sensor device which measures a degree of torsion of a measurement object by using a fiber Bragg gratings (FBG) sensor, the sensor device comprising: an FBG sensor including a sensing unit formed in one section of an elongated optical fiber; and a fixing device for fixing and supporting the FBG sensor to cause displacement of the FBG sensor according to motion of the measurement object, wherein the fixing device includes a bending prevention member to enable the sensing unit to have torsion displacement without bending displacement, according to the motion of the measurement object.
