Itmerges at the nano-scale into nanoelectromechanical systems (NEMS) andnanotechnology. MEMS are also referred to as micromachines in Japan, or microsystems technology (MST) in Europe.   MEMS are separate and distinct from the hypotheticalvision of molecular nanotechnology or molecular electronics. MEMS are made upof components between 1 and 100 micrometres in size (i.e. 0.001 to 0.1 mm), andMEMS devices generally range in size from 20 micrometres to a millimetre (i.e.0.02 to 1.0 mm). They usually consist of a central unit that processes data(the microprocessor) and several components that interact with the surroundingssuch as microsensors.At these size scales, the standard constructs of classicalphysics are not always useful. Because of the large surface area to volumeratio of MEMS, surface effects such as electrostatics and wetting dominate overvolume effects such as inertia or thermal mass.
