2. The current ultramodern technologies are focusing on
automation and miniaturization.
Smart dust are tiny electronic devices designed to capture
mountains of information about their surroundings while
literally floating on air.
The idea behind ‘smart dust’ is to pack sophisticated
sensors, tiny computers and wireless communicators into
a cubic-millimeter mote.
As the motes drift on wind, they can monitor the
environment for light sound and a wide range of other
information and beam that data back to the base station,
miles away.
3. Smart Dust requires both evolutionary and revolutionary
advances in miniaturization, integration, and energy
management.
Designers can use micro electromechanical systems to
build small sensors, optical communication components,
and power supplies.

5. The smart dust mote is run by a microcontroller that not
only determines the task performed by the mote, but
consists of the power to the various components of the
system to conserve energy.
It also turns on optical receiver to see if anyone is trying to
communicate with it.
Microcontroller will use the corner cube retro reflector or
laser to transmit sensor data or a message to a base station
or another mote.
Primary constraint in the design of the Smart Dust mote is
volume.
Add legs or wings to smart dust and we get micro robots.

7. Miniaturization effort could help solve one of the most
pressing economic problems of the day: run away energy
costs.
Sensors form a network relaying data.
Save nations on electricity costs.
8. Chemical or biological sensors.
Weapons stockpile monitoring.
Defense related sensor networks.
Land or space communication networks.
Monitoring environmental conditions that affect crops
and livestock.
Building virtual keyboard.
Internal space craft monitoring.
9. Research in the wireless sensor network area is growing
rapidly in both academia and industry.
Most major universities and many companies now have
sensor networking projects, and some products are
appearing on the market
