▎ 摘　　要

NOVELTY - The apparatus (100) has a graphene layer (130) arranged on a bonding layer (120). The bonding layer is arranged on a transparent substrate (110). The graphene layer applies fixed voltage for being heated with current flowing according to the graphene layer. A power supply unit applies voltage to the graphene layer. The bonding layer is covered with a hygroscopic agent in which the bonding layer absorbs moisture. A humidity sensor is arranged under the transparent substrate to sense reference humidity. The coating layer is coated with hydrophilicity material. USE - Graphene heating apparatus. ADVANTAGE - The apparatus improves optical permeability of an object so as to remove fogging or freezing generated on a surface of the apparatus. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a graphene heating apparatus. Graphene heating apparatus (100) Transparent substrate (110) Bonding layer (120) Graphene layer (130)
