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.

Strain sensor-based IMU sensor, and inertial measurement system comprising same

Embodiments relate to an Inertia Measurement Unit (IMU) sensor that generates strain information including a change in strain based on first output light of a first type of optical fiber sensing unit, calculates acceleration information of an object on which an IMU sensor () is mounted based on the strain information, generates angular velocity information based on output light of a second type of optical fiber sensing unit, and calculates angle information of the object based on the rotational speed information.

Optical fiber sensor-based inertial measurement system

A motion capture system includes a motion sensor having a flexible body and a fiber bragg gratings (FBG) sensor inserted into the body, a fixture configured to fix the motion sensor to a human body of a user, a light source configured to irradiate light to the motion sensor, and a measurer configured to analyze a reflected light output from the motion sensor, wherein the FBG sensor includes an optical fiber extending along a longitudinal direction of the body and a sensing unit formed in a partial region of the optical fiber and having a plurality of gratings, and wherein a change of a wavelength spectrum of the reflected light, caused by the change of an interval of the gratings due to a motion of the user, is detected to measure a motion state of the user.
