INTRODUCTION
Observations say that when a device is made on a smaller scale we got the best of everything. Here we are going to introduce those technologies and their advancements and application,which will make it possible on atomic precision. This is the new developoing technology,which combines the Engineering and chemistry for new industrial revolution. MEMS,or Micro electrical and mechanical systems, are i8ntegrated systems combining both electrical and mechanical components. Microelectromechanical systems is the integration of mechanical elements, sensor, actuators, and electronics on a common silicon substrate through microfabrication technology.
NANO-MEMS are the nanostructured electromechanical devices, which relates nanotechnology with micro electro mechanical systems. NANO-MEMS should let us make almost every manufactured product faster, lighter, stronger, smarter and cleaner. It is focusing on projects, I which can be implemented in bettering our lives.
WHY WOULD WE DEVELOP IT?
Precision has been mentioned as benefit of molecular machnaics and is one of the keys to understanding why we would want to develop this technology. Technology hs never had this kind of precise control; all of our tecvhnologies today are bulk technologies. We take a lump of something and add or remove pices until we are left with whatever object we were trying to create. In this application, precision menas that there is a palce for every atom and every atom is in its place. Schematics will be detailed, and there will be no unnecessary parts anywhere in the design. We wil use machanics of precision to create products of equal precision. With this precision, we should be able to recycle all of the waste products produced by the manufacturing process and put them to go use elsewhere. Manufacturing will also become less expensive as a result additional benefits arise when we consider the size of devices that we will able to create. Once we are working on the atomic scale, we can create machines that will go polaces into smaller and smaller spaces, and we will be able to do much with much less. NANO-MEMS promises unprecedented and efficient control over our environment, but taking advantage of anticipated developments requires forethought and planning.
PRACTICAL APPLICATION IN VARIOUS FIELDS:
OPTICAL FIBER TECHNOLOGY:
The communication technology market is and will continue to experience as explosive growth in the optical fiber communication arena; NANO-MEMS will play a key and critical role in the creation of the all-optical networks. In the near future one will also find NANO-MEMS in wire less personal communication system. To further enable NANO-MEMS solution for these and other application two critical technology are required; micro actuators and three dimensional silicon micro machining based on integrated circuit fabrication techniques. A new fabrication process that integrates silicon bulk micro machining with poly silicon surface, micro machining has been developed to create complex three dimensional silicon structures. Fiber Optics telecommunication is a major application of optical fibers. Optical fibers also finding applications in local area network; imaging and display; fiber coupled medical devices and medical lasers and other fiber coupled optical diagnostic medical devices; and, fiber-based sensor technology.
