Abstract
The present application discloses a hydrophobic insulation layer of a biochemical sensor, which is adhered between an electrode group and a cover plate, and comprises a polyethylene terephthalate (PET) film, a first pressure-sensitive adhesive layer coated on a first surface of the PET film for adhering to the electrode group, a resin layer coated on a second surface of the PET film for adhering to the cover plate through a second pressure-sensitive adhesive layer, wherein the resin layer is selected from paraffin wax, the elements of which must be carbon (C) and hydrogen (H), and the melting point of the paraffin wax must be between 40-70℃, so that the resin layer has hydrophobic properties and the biochemical sensor does not peel off during use.
