The development of a university of Cambridge, UK, electronic ink used for printing of graphene materials.Because of graphene only atom thick, and the price is low, has great advantages in terms of electronic ink. 
It is reported that this kind of ink made of graphene has many characteristics, such as flexibility, optical transparency, and electrical conductivity. 
According to the report, the research and development for patients need a heart monitor, would be a boon.Because made of graphene electronic ink monitor can be easily embedded in clothing.In addition, this material can also be used for the airport baggage tracking purposes. 
Conductive ink is made of silver and other precious metals prices are very expensive.Graphene, by contrast, has the advantages of the low cost, stable performance, and does not require too much India post-processing step.
