Abstract: Disclosed is a method for fabricating a wearable hydrogel glucose sensor, belonging to the technical field of biomedical sensing, including using polyacrylamide hydrogel as a basic material, preparing a hydrogel film by adding with phenylboronic acid group capable of recognizing glucose molecules, and carrying out grating writing on the hydrogel film in a femtosecond laser direct writing mode to obtain the wearable hydrogel glucose sensor. The hydrogel film combines with glucose and expands linearly, which makes the grating period and effective refractive index change. The quantitative measurement of glucose is realized by detecting the spatial position of diffraction band and the change of diffraction power intensity.

Abstract: Disclosed are a data analysis method and a data analysis system for retinal nerve fibrous layer. The method comprises the following steps: obtaining a peripapillary RNFL scanning image and a full-circumference RNFL thickness measurement data distribution image; obtaining a fundus scanning image, measuring a optic disc macular inclination angle; obtaining the upper and lower range of the RNFL scanning image, and measuring the upper and the lower RNFL thickness; obtaining an intersection position of an RNFL measuring ring and a blood vessel according to the canning image, and respectively correcting the upper and the lower RNFL thickness; performing a symmetry evaluation of the upper and the lower RNFL thickness according to the upper and the lower RNFL thickness correction value, and judging whether the RNFL data is abnormal. The system includes: image acquisition module, macular angle module, RNFL thickness module, RNFL thickness correction module and RNFL data evaluation module.
