Nano Electromechanical Systems and Its Applications

1. ABSTRACT:

Nano electromechanical systems are devices that operate like normal electromechanical devices alone are built on the nanoscale or even the element scale. Controlling and building much(prenominal) devices require advanced applied science that is still facing a lot of challenges

2. INTRODUCTION

Nano technology is defined by the National Nanotechnology initiative as intellect and control of social occasion at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications. Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale.

The importance of nanoscale technology is the idea that all properties of material up o the molecules muckle be used.

Nanoelectromechanical systems, withal known as NEMS, are basically electro mechanical systems such as switches and transistors that are scaled to nano or even atom size [1]. Nanoelectromechanical systems are evolving, with new scientific studies and technical applications. In general, all mechanical devices are shrinking in burdensomeness and width to reduce mass, this is needed to reduce mass and set down the force constants of these systems. The main advantage of Nanoelectromechanical systems is that its flexible properties allow it to door to fundamental frequencies in the microwave range which vary from 0.3GHz to 300GHz. other advantage is the high mechanical quality factor `Q which stub easily be in the tens of thousands or higher; another(prenominal) advantage is the active masses in the femtogram range which is A

Even though this science is still growing, it is still chthonic experiments to find methods of build and control such systems with...
