Nanocircuits are nanoscale electrical circuity. The first programmable nanoprocessor was unveiled in 2011, though commercial applications may be a decade or more off. Organic nanostructures such as graphene are likely to replace silicon as the material of choice for circuits. Even accounting for their size, nanocircuits consume relatively little electricity compared to traditional circuitry. Thanks to their lighter energy requirement and tiny size, naocircuits will enable smaller and lighter phones, computers and sensors, and will significantly increase computing power.
