Описание: The advances of microelectromechanical systems (MEMS) and devices have been instrumental in the demonstration of new devices and applications, and even in the creation of new fields of research and development: bioMEMS, actuators, microfluidic devices, RF and optical MEMS. Microelectromechanical systems, also written as MEMS, is the technology of very small devices; it merges at the nano-scale into nanoelectromechanical systems (NEMS) and nanotechnology. MEMS are made up of components between 1 to 100 micrometres in size (i.e. 0.001 to 0.1 mm), and MEMS 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 surroundings such as microsensors. At these size scales, the standard constructs of classical physics are not always useful. Because of the large surface area to volume ratio of MEMS, surface effects such as electrostatics and wetting dominate over volume effects such as inertia or thermal mass. MEMS are already used as accelerometers in automobile air-bags. They have replaced a less reliable device at lower cost and show promise of being able to inflate a bag not only on the basis of sensed deceleration but also on the basis of the size of the person they are protecting. Basically, a MEMS device contains micro-circuitry on a tiny silicon chip into which some mechanical device such as a mirror or a sensor has been manufactured. Potentially, such chips can be built in large quantities at low cost, making them cost-effective for many uses. Experience indicates a need for MEMS book covering these materials as well as the most important process steps in bulk micro-machining and modeling. This comprehensive work entitled Microelectromechanical Systems and Devices encompasses various types of MEMS- and NT-based sensors and devices, such as micropumps, accelerometers, photonic bandgap devices, acoustic sensors, CNT-based transistors, photovoltaic cells, and smart sensors. The book focuses on the materials science of MEMS structures and the films involved to create those structures.
