The supercontinuum broadband light source be connected with first section single mode fiber, the other end of first section single mode fiber and the one end 13 butt fusion of little fiber coupler, the other end 15 butt fusion of little fiber coupler and the butt fusion of second section single mode fiber, the spectrum appearance is connected to the other end of second section single mode fiber. The invention combines the humidity sensitivity and elasticity characteristics of the CNT-PDMS compound with the strong evanescent field and the elasto-optical effect of the micro optical fiber coupler to realize the simultaneous and accurate measurement of humidity and stress. The invention has the advantages of high sensitivity, high response speed, anti-interference, high reuse rate and the like. The novel technology can be applied to the detection of the humidity and the pressure of the surrounding environment of the precise electronic device.
