Definition

• Nano means one billionth of a meter, or 10 -9
  meters.
• Nanotechnology is science, engineering,
  and technology conducted at the nanoscale, which
  is about 1 to 100 nanometers.
• The term nanotechnology is defined by Tokyo
  University of Science Professor Norio Taniguchi
  in a 1974 .

3
History

• In 1980 researchers reported the discovery of
  Bucky Ball, a round molecule of 60 atoms of
  carbon.
• This led in turn to the discovery of a related
  molecular shape known as Carbon Nanotubes in
  1991.

Types

• Nanotechnology is ubiquitous and pervasive. It is
  an emerging field in all areas of science,
  engineering and technology. Some are as given.
• Nano-Materials.
• Nano-Electronic.
• Nano-Robotics.
• Molecular mechanics
• Nano engineering

• Nanobiotechnology
• Nanofluidics
• Nanohub

5
Nano-materials

• Nanoscale materials can also be used for bulk
  applications most present commercial
  applications.
• The nanomaterials field includes subfields
  which develop or study materials having unique
  properties arising from their nanoscale
  dimensions.
• Nanoscale materials are sometimes used in solar
  cells which combats the cost of traditional
  Silicon solar cells

6
Nano - electronics

• Nano electronics is one of the major technologies
  of Nanotechnology. It plays vital role in the
  field of engineering and electronics.
• Nano electronics make use of scientific methods
  at atomic scale for developing the Nano machines.
• This is implied in the next-generation approach
  towards manufacture of MEMS, microprocessors,
  optical switching and several other electronic
  components.

• Some Consumer Products which are using
  Nanotechnology
• Computer Hardware
• Display Devices
• Mobile Communication Products
• Audio Products
• Camera Films
• The world market for Nano electronics is
  expected to reach 409.6 billion by 2015.

Nano Robotics

• A Nano robot is a tiny machine designed to
  perform a specific task or tasks repeatedly and
  with precision at nanoscale dimensions.
• They are Nano devices that will be used for the
  purpose of maintaining and protecting the human
  body against pathogens .

WHY ONLY NANOTECHNOLOGY FOR FUTURE ELECTRONICS?

• Today microelectronics are used and they solve
  our most of the problems. Then why do we need
  Nanotechnology?
• The two exceptional disadvantages of micro
  electronics are
• Physical size
• Increasing cost of fabrication of integrated
  circuits

12
FUTURE SCOPE IN NANOTECHNOLOGY

• Nanotechnology for flexible Electronics
• Nanotechnology for wireless devices
• Nanotechnology for molecular devices

13
NANOTECHNOLOGY FOR FLEXIBLE ELECTRONICS

• Stretchable electronics or flexible electronics
  is likely to be the future of mobile electronics.
• In the future, it is likely that graphene will
  become a dominant material in flexible
  electronics.
• Graphene is nothing but an
  allotrope of carbon that has superb electrical
  conductivity, flexibility, and physical strength.
• Potential applications include wearable
  electronic devices, biomedical uses, compact
  portable devices, and robotic devices.

14
NANOTECHNOLOGY FOR WIRELESS DEVICES

• Visions of the wireless industry aims at ambient
  intelligence computation and communication
  always available and ready to serve the user in
  an intelligent way.
• All these requirements combined lead to a
  situation which cannot be resolved with current
  technologies. Nanotechnology could provide
  solutions for these new technologies.

15

• SENSORS
• Micromechanical sensors became
  an elementary part of automotive technologies in
  mid 1990, Within next ten years the development
  of truly embedded sensors based on nanostructures
  will become a part of our everyday intelligent
  environments. Nanotechnologies will enable new
  materials and new sensing elements for
  sensors.Nanosensors will have applications in
  many industries, among them transportation,
  communications, building and facilities, safety,
  and national security, including both homeland
  defense and military operations.

16

• MORE MEMORY
• 
  Already today mobile phones require a
  considerable amount of storage capacity to retain
  pictures, video, music, and data from a number of
  different applications. mobile phones will
  require up to 10 GB internal mass memory for
  short term and 50 -100GB for mid and long terms.
  Today flash memory is dominant and has been most
  reliable for portable devices. But it is
  predicted that in near future nanotechnology will
  help increasing the memory storage capacity to a
  phenomenal level by inventions like atomic
  holographic optical storage nanotechnology
  memory, etc. where terabytes and petabytes of
  data could be stored.

17
Overview

• No one knows the future of Nanotechnology for
  sure. History shows that science and technology
  impact society, but there is no way to predict
  what new scientific discoveries are next how
  technology will be used.
