Graphene, which is, in simple terms, a sheet of pure carbon atoms and currently the world’s strongest material, is one million times thinner than paper; so thin that it is actually considered two dimensional. Researchers in Bangalore , India , have discovered that sheets of graphene have unexpected " self - healing ' properties . After first subjecting sheets containing various defects to tensile stresses , they found that the broken graphene bonds in the defective areas began to repair themselves once the stresses were relaxed . “ We were able to document the self - healing of cracks in graphene without the aid of any external stimulus and at room temperature , ” said Dr. Swati Ghosh Acharyya , the main author of the article , which was published in Open Physics . The property could lead to artificial , self - healing skin for robots being developed .
