Abstract
Glucose extraction patch and its manufacturing process are provided. The patch comprises two gel discs containing enzymes that react with glucose to produce hydrogen peroxide, a frame for having two holes for accommodating the discs, a supporter for holding the discs, and a flexible printed circuit. The printed circuit includes electrodes for contacts with the gel discs, terminals for electrical connection with a measuring device, and circuits for electrical connection between the electrodes and the terminals. The electrodes are formed on the printed circuit by silk screening. Preprocessing may be applied to the electrodes after they are formed on the printed circuit.

13. A glucose extraction patch manufacturing process comprising:
-
a first step wherein said hydro gel discs are put into holes in said frame provided for accommodation thereof;
a second step wherein said terminals as wells as said circuit patterns are formed with copper wire on flexible circuit board film;
a third step wherein a mask with an electrode pattern made of a first material is set on the surface where said circuit patterns are formed, and ink made of said first material is sprayed thereon and then cured;
a fourth step wherein said third step is repeated for each electrode material;
a fifth step wherein said film with electrodes formed on it is cured for a predetermined period of time; and
a sixth step wherein said cured film is sprayed with adhesive except for the electrode parts, and then adhered to said frame containing said hydro gel discs. - View Dependent Claims (14, 15, 16, 17)
