▎ 摘　　要

NOVELTY - The method involves carrying out hydrophilic pre-treatment process to a conductive electrode (101). A metal-organic framework material layer (102) is formed on the conductive electrode after hydrophily pre-treatment by one-step in-situ chemical growth process. A sensitive material layer (103) is formed on the metal-organic framework material layer, where material of the conductive electrode is a carbon nano-tube fiber, a carbon nano-tube film, a carbon nano fiber film, conductive carbon cloth or a conductive graphene film. The conductive electrode is placed into concentrated hydrochloric acid after cleaning the conductive electrode. USE - Method for manufacturing a sweat electrochemical sensor for a wearable device (all claimed). ADVANTAGE - The method enables guarantying an electrochemical electrode with a high specific surface area, high dual-electric layer capacitance, excellent conductivity, simple and controllable preparation, high sensitivity and high stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a wearable device. DESCRIPTION OF DRAWING(S) - The drawing shows a structural schematic view of an electrochemical sensor sweat.
