  1. Smart Dust By Raymond Adorno For Dr Peel Material Science

  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

  4. 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.

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