Abstract (en)
[origin: WO2007000324A2] The invention relates to an optical strain gauge strip (D), made from a planar support layer (6) preferably of plastic and a cover layer (19) between which an optical fibre (2, 3, 4) has a frictional fit. The optical fibre (2, 3, 4) comprises at least one section (L) with a Bragg grating (5) for recording the strain on a deformable body or a different component region. The invention is characterised in that the optical fibre (2, 3, 4) is let into at least one guide channel (7, 8, 9) in the support film forming the support layer (6). Said guide channel (7,8, 9) with the optical fibre (2, 3, 4) and the Bragg grating (5) embossed therein is sealed with a covering film as outer layer (19), made from the same material as the support layer (6).
