What is Smart Dust?
Smart dust is a nano-structured silicon senor
which can spontaneously assemble, orient sense
and report on their local environment, which can
be used in a number of applications. Main
purpose is to collect and relay information.

1. Porous Silicon is etched by electrochemical
   Machining Process, which are used as
   concentrators what is analyzed.
2. The Silicon is chemically modified into a sensor
3. Reflective chemically modified mirrors are
   nano-structured into sensor to reflect a certain
   color when target is identified.
4. Sensors are oxidized making it hydrophobic
5. Sensors are broken into SMART DUST

• Each sensor has incorporated into it
• a microprocessor
• mini-battery source
• Two way transmitter
• Soon will be the size of a grain of sand named a
  mote.

Applications of Smart Dust

• Measure vibrations in pumps, compressors and
  engines and pass reading using wireless links to
  predict equipment failure.
• Monitor local temperatures
• Monitor speed and Volume of traffic
• Monitor presence of people
• Target contaminants in drinking water
• Relay information about cancerous cells
• Detect hazardous chemical and biological agents
• Military Applications
