A Presentation OnSMART DUST
CONTENTS Introduction Fabrication of Smart Dust Working Major challenges Applications Advantages & Disadvantages Conclusion
INTRODUCTION Smart Dust is a self-contained network of tiny motes each
having the capability of sensing and monitoring the environment conditions.
Smart Dust concept has been credited to researchers at the University of California, Bekerley in 1997 by Prof. Kris Pister.
They contain sensors which have the computational capability They can communicate with a base station or with other motes
depending on the application. The transmission is carried out by microscopic devices known
as micro electromechanical system (MEMS)

FABRICATION OF SMART DUST
WORKING
Smart dust motes run by a microcontroller.
Microcontrollers consist of tiny sensors for recording various types of data.
Sensors run by timers. Data is sent to the base controlling
station Corner Cube Retro-Reflectors (CCR)
built using MEMS technique
MAJOR CHALLENGES
It is difficult to fit all these devices in a small Smart Dust both size wise and Energy wise.
As the devices are so small, batteries present a massive addition of weight.
APPLICATIONS
Environmental protection Habitat Monitoring In hospitals In military Security Virtual keyboards
Circulatory Net
SMART DUST
Virtual Keyboard
FOREST FIRE DETECTION
IMPLEMENTATION Drop a smart dust from an
airplane Motes self-organize into a
network
USAGE A mote that detects a fire
notifies central monitoring station
The mote location is the approximate location of the fire
SPOTTING PIPE CORROSION
Benefits Inspect pipes
without crawling in tight spaces.
No need to remove insulation to
inspect pipe
ADVANTAGES
Small Size Better Connectivity Low Cost
DISADVANTAGES
The main concern is privacy. Because it is so tiny, this device can be used to spy on people without their approval.
Another concern is the security of the information transmitted through this sensors. Like in any other computer, hackers can brake into the system and steal or modify important data.
CONCLUSION
There are many ongoing researches on Smart Dust, the main purpose of these researches is to make Smart Dust mote as small as possible and to make it available at as low price as possible.
