So what are MEMS? Microelectromechanical systems (MEMS) • small integrated devices or systems that combine electrical and mechanical components • range in size from the sub micrometer (or sub micron) level to the millimeter level, and there can be any number, from a few to millions, in a particular system • MEMS extend the fabrication techniques developed for the integrated circuit industry to add mechanical elements such as beams, gears, diaphragms, and springs to devices.
