Abstract: 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.

Abstract: 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.
