  • Patent number: 11832941
    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.

  • Publication number: 20050025894
    Abstract: The invention relates to the design and manufacturing technique of mechanical component which is prone to be worn in relative movement. More particularly, it relates to a method of improving the wear resistance performance of the surface of mechanical component. In this method, a bionic non-smooth morphology is formed on the frictional surface of the mechanical component. That is, a plurality of convex units shaped as crown, dimple, scale, mesh, stripe and so on are distributed on the surface. These units are 0.01-2 mm higher than the base surface. The distributed density (S) of the units, i.e., the ratio of the geometrical area of the convex units projected on the surface of the base with respect to the whole surface area of the base, is 10-40%. The hardness difference between the units and the base is HB0-200. It breaks through the conventional concept and provides a more rational and effective way to improve the wear resistance performance of mechanical component.
