The statistical results of the field of Chinese FBG sensing technology were visualized by using patent analysis method and parsed the technology background of FBG sensors. Several statistics in 17 parameters system were completed, which include the current status, R&D teams, and application fields of the patents of FBG sensors. The statistical results indicate that the FGB sensing technology are currently in the development of the technology life cycle; the R&D focus concentrates on the sensor designing and sensor array system; college labs account the most R&D teams; the application field includes the composite and concrete structure monitoring, the performance monitoring of smart material, power industry, pharmaceutical industry, and chemical industry. With the gradual increase in R&D, gradually mature in technology, the FBG will in the mature of the technology life cycle; and wavelength demodulation device will be an significant direction of development of FBG sensing technology.
