A nanocomputer is a computer whose physicaldimensions are microscopic.

The field of nanocomputing is part of theemerging field of nanotechnology .

Several types of nanocomputers have been suggested or proposed by researchers and futurists.

3

Nanotechnology is all about building things

atom by atom & molecule by molecule.

Goal of this technology is to make tiny devicescalled ‘Nanomachines’.

When manufacturing products made from an atom, the property of those products depends on how those atoms are arranged.

4

Electronic Nanocomputers

Chemical & Bio-Chemical Nanocomputers

Mechanical Nanocomputers

Quantum Nanocomputers

5

Electronic nanocomputers would operate in a manner similar to the way present-day microcomputers work. The main difference is the physical scale.

To further decrease the size the concept, “Nanolithography” will be needed.

6

Chemical and biochemical computers would store and process information in terms of chemical structures and interactions.

Biochemical Nanocomputers seems far off because the mechanisms for animal brains are not properly understood by human.

In general terms, chemical computer is one that process information in terms of making and breaking chemical bonds & store resulting information in terms of chemical struture.

7

Tiny Machines & computers would be assembled bythe Mechanical Positioning of atoms or molecular

building blocks, one atom or molecule at a time.

Mechanical Nanocomputers would use tiny moving components called Nanogears to encode information.

8

A Quantum Nanocomputer would work by storing data in the form of atomic quantum states or spin.

Technology of this kind is already under development in the form of single-electron memory (SEM) and quantum dots.

9

To make ever smaller computing components.To understand computing under uncertainty and

with faults.

To model and analyze non-deterministic assembly.

To cope with faults. To communicate with physical

nanotechnologists.

There are two different approaches to building things inthe nanoscale. They are:

(FOW’s carry info in the form of light)

(Solids form out of a gaseous phase)

Although we can build Nanowires using either approach, no one has found a way to make mass production feasible.

15

The small scales make it very difficult to build transistors automatically right now, engineers usually manipulate wires into place with tools while observing everything through a powerful microscope.

The company Apple has released an experimental device called Nanocomputer iLens that aims to facilitate and improve vision of the human being.

This Bionic contact lens has photographic memory, binoculars, night vision and augmented reality with a heads up display.

Running with the basic functions of a computer, this is why Apple research team called it a nanocomputer.

There is still a lot to develop in this app.

Here is the type of vision you can get using theselenses.
