Korean research team has successfully developed a technique to make a new material that can measure brainwaves without making an incision into a patient’s scalp. A research team headed by Dr. Lee Hyung-jung from the Korea Institute of Science and Technology (KIST) announced on Feb. 11 that they have succeeded in developing a new material with a mesh structure capable of detecting even weak biosignals when attached to a human skull. It was done by combining a single-layer carbon nanotube and a substance that the team calls P8GB#1.

Biosignals from a brain, a heart, and muscles are usually delivered in the form of ions. It is possible to get various kinds of information by changing ion signals into electronic signals and analyzing the result using electronic devices. The research team discovered P8GB#1, a substance with a tendency to stick to single-layer carbon nanotubes, producing a highly-conductive nanomesh. The material with a minute mesh structure can detect electronic signals owing to the large contact surface.

KERI’s nanomaterials ready for mass production

Big things come in small packages. As man expands the world and discovers new possibilities, size becomes an essential property of our technological revolution. With the emergence of new technologies, miniaturization is the name of the game. 

February 16, 2012 marks the eventful agreement between Dr. Lee Keon-woong who leads his Nano Hybrid Technology Research Center at the Korea Electro-technology Research Institute (KERI) and Sang Bo Corporation (Sang Bo). This agreement allows for mass production and commercialization of graphene, one of the most prominent and desired nanomaterials of the current age. It will provide the soft electronic technology necessary to produce computers that can be folded, fitted into bags, and even wound around wrists.

National Consensus on Graphene’s Significance 

Graphene is a two-dimensional nanomaterial with the thickness of a single atom. Its quantum mechanical structure possesses excellent electric, physical, and chemical features, making it the most ideal material for application due to its high electric conductivity and charge mobility. This finding led to an explosion of related studies over recent years. Hence, the technology has been the center of attention in both public and private sectors. The Korean government launched a KRW 210 billion program to develop graphene and to promote this technology. Under this national consensus and drive to enhance this technology, KERI, one of the leading national public research centers, joined forces with the most renowned company in graphene manufacturing.
