Abstract

This invention relates to a fiber optic strain sensor for sensing plane strain in at least one direction, as well as a sensor package and related systems. The strain sensor comprises an optical fiber (1) including at least one Bragg grating (FBG1) responsive to mechanically induced strain, the strain responsive Bragg grating(s) being bonded to a polymer film (2) with a defined direction on the film with respect to one outer edge of the film, said fiber forming an essentially circular loop on the film, said at least one Bragg grating being positioned in a linear portion of said loop. The invention also relates to a temperature sensor (3) especially for use in relation to thestrain sensors.
