▎ 摘　　要

NOVELTY - The sheet (108) has a flexible substrate. A graphene film is placed on the flexible substrate through an adhesive film. A nano-scale plating circuit is electrically connected to the graphene film. A substrate trench has two substrate sidewalls intersecting at the bottom of underlying substrate trenches. The substrate sidewall serves as a bearing surface of a printed conductor sidewall. The substrate sidewall extends from the printed conductor sidewall in the direction toward the associated substrate trench bottom. USE - Graphene heating sheet for smart clothing used in aviation and military fields. ADVANTAGE - The far-infrared radiation emitted by the graphene heating sheet does not harm the human body, and also has good health care effects that improve the body's microcirculatory system and promote metabolism. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphite heating sheet. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a smart clothing functional module.
