The invention belongs to the technical field of robot sensing and measurement and discloses a fiber bragg grating monitoring device and method for flapping deformation of a flapping-wing robot in flight. A first flapping wing and a second flapping wing are respectively assembled on the left and right sides of a trunk part; a first array polymer fiber bragg grating, a second array polymer fiber bragg grating, a third array polymer fiber bragg grating and a fourth array polymer fiber bragg grating are respectively implanted in the first flapping wing and the second flapping wing; an optical fiber connector is arranged at an upper part of the trunk part and is connected with a multi-core quartz optical fiber; the other end of the multi-core silica fiber is connected with one end of a fiber grating wavelength demodulator; and the fiber grating wavelength demodulator is used for demodulating and outputting a transmitted grating signal. According to the device, a polymer fiber grating implantation mode is adopted, and high-precision and spatial-constraint-free real-time measurement of flapping deformation can be realized.
