▎ 摘　　要

NOVELTY - The patch has a function module for realizing the sweat detection, a flexible patch module for packaging the function module, a locating module, and a mobile terminal. The flexible patch module comprises a viscous film (2), and a flexible epithelium (3). The function module comprises sweat drug detector (1), a heating layer (4), a lithium battery (5) and a single chip processing unit installed between the adhesive film and the flexible epithelium, and a buzzer (6). The locating module comprises a Beidou satellite positioning system and the SIM card slot. USE - Patch for detecting drug based on sweat. ADVANTAGE - By installing the lithium battery, the user charges at any time, by the way of sticking sheet, it can be tightly contact with human body skin and detects human body with non-toxic, using polyacrylate pressure-sensitive adhesive realizes tight joint and avoid the condition of the user skin allergy much as possible. The glassy carbon electrode modified by the used graphene nano sheet has fast response speed, stable signal, high sensitivity, low cost, simple preparation method. It does not need to use specific reagent, separating or pre-processing, the public security department directly checks the user position and whether there is virus-absorbing situation through the information sent by the mobile terminal, the measurement and control result can be very accurate, has comfortable wearing, real-time monitoring, timely warning, data real DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the patch for detecting drug based on sweat. 1Sweat-liquid drug detector 2Viscous film 3Flexible epithelium 4Heating layer 5Lithium battery 6Buzzer 7Single-chip microcontroller
