Researchers from the Department of Engineering at the University of Oxford have developed a new technology that goes beyond wireless advancement and that allows for the transmission of data between electronic devices and has the potential to eliminate the need for power and data cables completely.
This technology is the result of the team’s study of metamaterials, man-made materials that have properties that natural ones don’t. The team studied metamaterials that acted as magneto-inductive wave guides and magneto-inductive power surfaces. These kinds of inductive materials are similar to those found in the charging unit of your electric toothbrush. (These materials not only charge, but can transfer data as well.)
By embedding copper coils in a conductive layer of material to form a sealed circuit board, you can create a chip with no legs and pins that can be glued onto a metaboard. The new surface technology can achieve a data-transfer rate of 3.5 gigabits per second and hundreds of watts of power. “The circuits have the capacity for increased performance,” said Dr. Chris Stevens, lead researcher on the team.
