2. 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.

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

5. 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.

6. 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
