However, for fiber-optic MEMS hydrogen sensors driven by thin-film strain, performance assessment based solely on pure hydrogen response is insufficient for practical use because
Abstract and Figures A high sensitive fiber-optic strain sensor, which consists of a cantilever, a tandem rod and a fiber collimator, was proposed.
For strain sensing the FBG has to be bond to the object under test firmly, and the influence of temperature has to be compensated by an additional temperature sensor, e.g. a second FBG.
A highly sensitive sensor, which can detect the temperature and strain simultaneously, is proposed using a hollow-core anti-resonant fiber with composite nested tubes.
The strain sensor responses show an approximate correlation with those of the temperature-compensation sensor because of the identical material that was used in both the
