8.  Advantages of MEMS:  MEMS applications: Why MEMS? Low cost Small size, low weight, high resolution Low energy consumption, high efficiency Multi-function, intelligentized Automobile industry Medical health care Aerospace Consumer products RF telecommunications Other areas

9. Nanotechnology  Nanotechnology: a field of applied science and technology whose unifying theme is the understanding and control of matter on the atomic and molecular scale, normally 1 to 100 nanometers, and the fabrication of devices within that size range.  Nanotechnology is a general-purpose technology which will have significant impact on almost all industries and all areas of society. It can offer better built, longer lasting, cleanser, safer and smarter products for home, communications, medicine, transportation, agriculture and many other fields.
