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
