The king of new material – Graphene, is regarded as the most subversive material in 21th century. In recent years, the researches of IBM have found that Graphene can absorb and radiate up to 40% far infrared ray. Human body is a good absorber of far infrared ray, and the main absorption band is 3-15um where the graphene far infrared ray works. When heated, the graphene will radiate 8-15um far infrared wave which has the function of activating body cell nucleic acid protein and other biomolecules.
