摘要:
The present disclosure provides an apparatus for sensing a motion. The apparatus comprises an optical fibre portion comprising a Bragg grating and an element for reducing an impact of an external force that is transversal to the Bragg grating. Further, the apparatus comprises a contact region arranged so that movement of a further region, that is in direct or indirect contact with the contact region and moves in a direction along a portion of the apparatus, causes movement of the optical fibre portion at the contact region. The apparatus also comprises a holder arranged for reducing movement of the optical fibre portion at a holding region when the optical fibre portion is moved at the contact surface. The apparatus is arranged so that movement of the contact region relative to the holding region causes a change in strain of the Bragg grating.
