Abstract
Material Science research is now entering a new phase where the structure and properties of materials can be investigated, characterized and controlled at the nanoscale. New and sometimes unexpected material properties appear at the nanoscale, thus bringing new excitement to this research field. In this talk, special emphasis will be given to one-dimensional nanotubes and nanowires because they exhibit unusual physical properties, due to their reduced dimensionality and their enhanced surface/volume ratio. These unusual properties have attracted interest in their potential for applications in novel electronic, optical, magnetic and thermoelectric devices.
Another feature of nanotechnology is that it is the one area of research and development that is truly multidisciplinary. Research at the nanoscale is unified by the need to share knowledge on tools and techniques, as well as information on the physics affecting atomic and molecular interactions in this new realm.
So now we are going to introduce the nano technology into the field of robotics to achieve realistic movements which is a real dream of the human for more than 5 years. By introducing this nervous system to the robot we have exactly 2 advantages that is we can pass information same time and we can also the movements at the same time the cars reached the actual part where the movement as be caused. So we need have some knowledge about nano technology and from these we are going to see what the nano cars means and then how we are going to see the introduction of the nano cars into the neuron system.
Introduction to nano technology:
From converting sunlight into power to clean oceans, to monitor thermal environment, and to sensors in the form of biochips built into the human body performing as lifesavers by self-monitoring and guarding, nanotechnology assures us a lot more!
Stone Age, Bronze Age, Iron Age, Silicon Age, and next what? Nevertheless to say, we are well in to the Nanotech Age, where materials are just getting smarter day by day. There would be sensors embedded in almost all walks of life. Each element would be smart enough to repair itself as and when required. All this would be possible by manipulating matter at the molecular scale.
Scientists will now like to understand how simple atoms and molecules come together and arrange themselves to form complex systems, such as living cells that make life possible on earth. This approach deals with how complex systems are built from simple atomic-level constituents which result in nanoscience and nanotechnology. In simple, it is the study of properties of a few tens of atoms in a space of less say 50nm. Manufactured products are made from atoms. The properties of those products depend on how those atoms are arranged. If we rearrange the atoms in coal we can make diamond. If we rearrange the atoms in sand we can make computer chips. If we rearrange the atoms in dirt, water and air we can make potatoes. Almost any manufactured product could be improved, often by several orders of magnitude, if we could precisely control its structure at the molecular level. We often want our products to be light and strong.
What is nanotechnology?
Nanotechnology is a molecular manufacturing or, more simply, building things the size of one atom or molecule with programmed precision. It involves working with matter at scale of one- billionth of a meter
Nanoscience is concerned with nonmaterial’s that have atleast one of three dimensions of about 1 to 10 nanometers. The word 'nano' comes from the Greek word "nanos" meaning 'dwarf'. The term nano is the factor 10-9 or one billionth. Nanotechnology is that area of science and technology where dimensions and tolerances in the range of 0.1nm to 100 nm play a critical role'. Nanotechnology can best be considered as a 'catch-all' description of activities at the level
Nanotechnology is an anticipated manufacturing technology giving through, inexpensive control of the structure of matter. The term has sometimes been used to refer to any technique able to work at a submicron scale here it is used in the more usual sense of general control of the structure of matter on a nanometer scale-that is, a broad ability to control the arrangement of atoms. This ability will require development of devices termed 'assemblers'.
Nanomachines:
The idea of nanotechnology is therefore to master over the characteristics of matter in an intelligent manner to develop highly efficient systems. However, this is a big challenge to technology as to how to build material in bulk form this way. It will be easy if one can learn through bioscience how the nature does it. Proteins are molecular machines that routinely manipulate individual atoms. Synthesis of building blocks of proteins can provide us an appropriate technology for making nanomaterials in bulk form. Molecular nanotechnology draws on cutting-edge advances in physics, chemistry, biology and computer science to build structures measured in nanometers.
Though we haven’t reached that omnipotent stage of evolution, we still have plenty of nanotech applications, from biosensors in the human body to intelligent systems embedded in real-time cars and airplanes calculating the wear and tear on engine life, everyday stain-resistant clothes, super telecommunication systems, and not to forget ‘smart dust’.
Nanotechnology – MEMS:
Micro-electromechanical system (MEMS) combines computers with tiny mechanical devices such as sensors, valves, gears, and actuators embedded in semiconductor chips. These elements are embedded in the mainframe of the system for carrying out the bigger tasks, they are usually referred to as ‘smart matter’.
This smart matter is used as micro information seekers (MIS). Since micro information seekers are minute and are termed as ‘motes’, motes are wireless computers small enough to be integrated into anything to create robust wireless networks. Assume a room in an office building to have a hundred or even a thousand light-and temperature-sensing motes, all of which would tie into a central computer that regulates energy usage in the building.
