NOVELTY - Non-invasive wearable glucose sensor has signal sensing unit. The signal sensing unit includes substrate (11), first conductive sheet (1), and second conductive sheet (2) for detecting bio-signal of glucose from sweat. The electrode unit (3) located on both ends of the upper, lower, or upper and lower portion of the signal sensing unit, supplying a current to the signal sensing unit, and obtaining a sensed bio-signal. The first conductive sheet is formed on the substrate and includes at least one conductive material selected from silver, copper, nickel, aluminum, silver nanowire, copper nanowire, nickel nanowire, graphene, and conductive carbon. The second conductive sheet includes one or more metal nanowires selected from copper nanowire, silver nanowire, and nickel nanowire, which are simultaneously formed on the surface or inside and on the surface of the first conductive sheet. The second conductive sheet has a content per unit area of 3-800 mu l/cm2. USE - Non-invasive wearable glucose sensor used in glucose concentration measuring device (claimed). ADVANTAGE - The non-invasive wearable glucose sensor is used to measure the concentration of glucose in the sweat of the human body with high sensitivity and high precision by using current change with excellent selective binding force with glucose, and also commercialized for miniaturization and home use, has excellent wearability, and cost-effective and large-scale due to a simple manufacturing process.
