Scientists have used carbon nanotubes as the basis for high-speed thin-film transistors printed onto sheets of flexible plastic, a method which may allow large-area electronic circuits to be printed onto almost any flexible substrate at low cost and in mass quantities.

The University of Massachusetts Lowell and Brewer Science, Inc. scientists printed transistors with a speed of 312 megahertz, significantly faster than the kilohertz speeds seen in other semiconducting polymers.
