Title:
IMPLANTABLE ELECTROCHEMICAL BIOSENSOR, TEST METHOD, AND IMPLANTABLE MEDICAL INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2023/246519
Kind Code:
A1
Abstract:
An implantable electrochemical biosensor (100), a test method, and an implantable medical instrument. The implantable electrochemical biosensor (100) comprises an electroactive domain (5), and a working electrode (1) and a reference electrode (4), which are separated by means of an insulating layer (3), wherein the working electrode (1) and the reference electrode (4) are respectively in contact with the electroactive domain (5). The implantable electrochemical biosensor (100) further comprises a flexible conductive film (2), which is electrically connected to the reference electrode (4) and is not in direct contact with the working electrode (1). In the test method for an implantable electrochemical biosensor (100), a reference electrode (4) is electrically connected to a test assembly by means of a flexible conductive film (2). In an implantable medical instrument using an implantable electrochemical biosensor (100), the implantable electrochemical biosensor (100) may be in a bent state, and a reference electrode (4) is electrically connected to the implantable medical instrument by means of a flexible conductive film (2).
