Title:
MINIATURIZED BIOSENSOR AND SENSING STRUCTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/001292
Kind Code:
A1
Abstract:
A sensing structure of a miniaturized biosensor (10), which is used for subcutaneous implantation in a living body so as to measure physiological parameters of a target analyte (310) in a biological fluid, and which may use an electrochemical reaction to reduce the interference of measurement by an interferent (320) in the biological fluid. The sensing structure comprises: a substrate (110) which has a surface; a first working electrode (120) which is disposed on the surface and which has a reaction surface; at least one second working electrode (130) which is disposed on the surface and is adjacent to at least one side edge of the first working electrode (120) for use in depleting the interferent (320) by using the electrochemical reaction; and a barrier layer (150) which is arranged at least corresponding to at least a part of the reaction surface so as to restrict the diffusive distribution of the interferent (320) when the biological fluid flows through the second working electrode (130), wherein the interferent (320) in the biological fluid passes through the second working electrode (130) over a period of time, and is depleted by the second working electrode (130) by means of the electrochemical reaction.
