Fiber optic microbend sensors under the strong signal will bring about the fiber rupture, and the sensor will invalidate. To solve this problem, the self-repairing of the fiber optic microbend sensor was researched. A short wavelength light curing adhesive was designed. It has good optical, mechanical and adhesive performances. We put it into the hollow-center fiber embodied with fiber optical sensor. And an intelligent fiber optic microbend sensor with self-diagnosing and self-repairing functions was designed. Experimental results show this sensor has little repairing time, good repairing effect.
