Micro-Manufacturing Examples This chain of six microscopic gears can be used to drive micro-engines at speeds of up to 25,000 rpm. Longer chains can also be used in complex electronic locking mechanisms that are practically unpickable – each gear has to be precisely aligned in order to activate an electronic switch [Source: Sandia National Laboratories/SUMMiT Technologies ]Sandia National Laboratories/SUMMiT Technologies

Nano-technology: Silicon composite structures [Source: Univ of Cambridge Nanoscale science labs, Mark Welland & Ghim Wei Ho ] Nano-technology is used to produce materials with feature sizes below 1 , typically in the range 1-100nm. The fabricated objects may have many uses, including catalysts, coating for clothes, medicine, etc.
