Smart Dust History

• Conceived in 1998 by Dr. Kris Pister of
  University of California Berkeley
• Funded by DARPA Defense Advanced Research
  Project Agency
• Powering Issue

Smart Dust Overview

• Merger of Computers, Mechanics and electrics with
  miniaturization technology
• Its core is small, low power Computer
• This Computer monitors the sensors embedded in
  the same chip
• Uses RF link for communicating and transmitting
  necessary information along with MEMS embedded in
  the same chip

6
Components Specifications

• A small, low power computer, with a operating
  system called Tiny OS.
• Sensors
• Battery
• Reflectors and transmitters for reflecting the
  laser beams
• And other as per requirements of the dust

Smart Dust Working

• Motes are run by Microcontrollers
• Microcontrollers takes the reading from the
  sensors, processes it and stores it
• It uses optical receiver to receive the messages
  from other motes
• It uses corner cube retro reflector or Laser to
  transmit sensor data to other motes

10
Smart Dust working

• The batteries are the basic powering devices in
  the motes
• The motes are in sleep mode most of the time with
  a little consumption of a few micro amps
• Counters and timers periodically trigger on the
  sensors which take the readings, micro-controller
  transmits them, stores them and the mode again
  goes to the sleep mode

11
Applications

• Military
• Smart Office Spaces
• Environmental Applications
• Diagnosis of Human Problems
• Security Purposes
• Conservation of resources
• And many more..

12
Smart Military Operations

• Can be used to sense enemy movements
• They can help to collect battlefield intelligence
• Can be proved as a weapon against bioterrorism
• Can be proved as brilliant spies

13
Smart Environment

• Can be used as seismic sensors
• Can be sewn in clothes to sense the working
  environment and change in it, so that the user
  can get better off it
• Can be used to identify the pollutants present in
  the environment
• Can make our life better by sensing these elements

14
Smart Medication

• Can assist a Handicap person about the paths
• Can assist in detecting and destroying tumor
  cells in the body
• Can help to identify Various type of diseases for
  whom the definitions are not yet given by
  defining them in the tiny OS and matching them

15
AD-HOC networks

• Smart dust can be used to form Ad-hoc networks,
  which can use radio link to transmit data
• These ad-hoc networks can be used in various
  fields where normal links are not possible
• Ad- hoc networks can be much cheaper than usual
  modes of certain applications

16
Future Goal

• In march 2003, this mote named Spec was made in
  which all the contents of a mote were fitted in
  less than 5 Sq mm, in less than a dollar. We can
  imagine motes to be as small as Dust Particles.

17
Future Goals

• Weather/seismological monitoring
• Internal spacecraft monitoring
• Land/space comm. networks
• Chemical/biological sensors
• Weapons stockpile monitoring
• Defense-related sensor networks

18
Conclusion

• Smart dust is the power of pc in a dust particle.
• Extent of miniaturization
• Can help us to lead a better life, in our own
  beautiful environment
