Embodiment 1

[0050] A packaging structure of a fibrous wearable sweat sensor. The carbon fiber with glucose oxidase fixed on the surface is used as the electrode core layer, and the cotton yarn is wound on the electrode in a helical shape. The distance between two adjacent helices is 10 μm. It is used for The detection limit of glucose in sweat is 50nmol / L.

Embodiment 2

[0052] A packaging structure of a fibrous wearable sweat sensor. Compared with Example 1, the difference is that the carbon fiber with lactic enzyme fixed on the surface is used as the electrode core layer, and several cotton yarns are wrapped on the electrode in parallel. The distance between the cotton yarns is 6 μm, which is used to detect lactic acid in sweat, and the detection limit is 500 nmol / L.

Embodiment 3

[0054] A packaging structure of a fibrous wearable sweat sensor. Compared with Example 1, the difference is that several cotton yarns are crisscrossed and coated on the electrodes, and the distance between two adjacent cotton yarns in the transverse direction is 6 μm. The distance between two adjacent cotton yarns in the longitudinal direction is 4 μm, which is used for the detection of glucose in sweat, and the detection limit is 50 nmol / L for sensing detection.

Abstract

The invention provides a packaging structure of a fibrous wearable sweat sensor. The structure comprises a fiber electrode core layer used for biosensing detection and a packaging layer wrapping the surface of the fiber electrode core layer, and the packaging layer has hydrophilicity and permeability and is used for transmitting a substance to be detected to the fiber electrode core layer to achieve biosensing detection. Preferably, the fiber electrode core layer is prepared by preparing a metal layer on the surface of a fiber base material and then impregnating the metal layer in a protein phosphate buffer solution; the metal layer on the surface of the fiber base material reacts under an acidic condition to obtain metal ions, and then the metal ions react with protein and phosphate to obtain a metal protein-based fiber electrode core layer. The packaging structure obtained in this way not only can protect the electrode material, but also can collect sweat and provide a stable detection environment for the working electrode, sensing efficiency and safety can be guaranteed, and preparation and integration of a flexible wearable device are facilitated.

Description

technical field [0001] The invention relates to the technical field of biosensing, in particular to a packaging structure of a fibrous wearable sweat sensor. Background technique [0002] Packaging is an essential processing technology in electronic devices. Its purpose is to optimize the appearance and performance of the product based on the application environment and usage requirements of the product. At present, flexible wearable electronic devices have attracted the attention of domestic and foreign researchers and the general public because of their characteristics of portability, sensitivity, flexibility, and continuous operation. However, the current research is mainly focused on realizing and optimizing the detection capability of the device itself, and there is still little research on the packaging of the device. [0003] Patent CN211560068U discloses a new type of fiber electrode, electrode buckle packaging mechanism and body parameter measurement clothing. The ...
