ABSTRACT

In the present world every country thinking of making there nation secured & safe. The

countries which were developed are investing much on the weapons, communication systems

e.t.c., to strengthen their strengths. But the countries which were still developing were unable toinvest such large investments.

The soldiers in the war weighing large weapons, huge weights. So, to these all problems a

solution is to be there. Yes, for every problem there will be a solution. Here for this problem thesolution is NANO TECHNOLOGY.

With the potential benefits of nanotechnology, both for social and national security

reasons, technologies are in development that enables early detection of hazardous conditions,

goods and human behaviors. Sensing and detection, surveillance, situational awareness,

interpretation, automated scene understanding are crucial aspects. In this paper we present theconcept of the future war weapons, military vehicles, unmanned vehicles & robots, armaments,

command & control, soldier warfare, human performance.

INTRODUCTION

Future military missions require its stake holders to do more with less. So

NANOTECHNOLOGY offers military stake holders

To get more performance, functionality, lifespan the present technologies need more size,

more space, more power, maintenance difficulty. So, NANOTECHNOLOGY gives you above

advantages with less weight, size, maintenance, power and cost.

WHAT IS MEANT BY NANOTECHNOLOGY?

Before going to the nanotechnology let us know about the meaning of NANO.

NANO means One billionth of meter.

NANOTECHLOGY is the technology which uses the particles of such nano-size to

implement in real time applications.

PARTICLES WHICH ARE USED IN NANOTECHNOLOGY

Quantum dots are nano scale

particles which change their

properties in some useful waywith the addition or removal

of an electron.

Carbon nano tubes are

stronger than steel, harder

than diamond, lighter than

aluminum, more conductive

than copper and a good

semiconductor (Ecole

Polytechnique)

Smart material that

changes its shape when

heated or automatically

responds to a specific

ADVANTAGES OF MINIATURISATION

As the nano materials are miniaturized in size they have some advantages.

They are as follows:

Miniaturisation delivers better products at a lower price:

Actually the researches done in laboratories that are in buildings gives results in days

duration.

But, in labs present in box gives results in hours, in labs present in chip gives you result in

minutes very accurately.

Miniaturization fasts the test and gives accurate results.

Nano materials are expected to greatly reduce the volume of

materials required by industry:

2. Canadian challenges such as Peacekeeping, Border Security, and Biothreat Early

Warning Systems can benefit from innovation employing nanotechnology and other

Technologies

DRDC funding can be leveraged by additional funding from other federal and provincial

agencies, the private sector and allied countries through a CANEUS-type initiative. This can

reduce time-to-market for new technologies and stimulate economic development in Canada.
