  1. SMART DUST -the Power of Pc in a Speck of Dust

  2. TOPICS COVERED: • ABOUT SMART DUST • GOALS • CONSTRUCTION • OPERATION OF MOTE • APPLICATIONS • ON THE DARKER SIDE • BIBLIOGRAPHY

  3. ABOUT SMART DUST: • Father of smart dust: Kris Pister • Based on MEMS: • Micro-Electro-Mechanical System

  4. GOALS: • To build a self-contained, millimeter-scale sensing and communication platform for a massively distributed sensor network.  • Will contain sensors, computational ability, bi-directional wireless communications, and a power supply, while being inexpensive enough to deploy by the hundreds.

  5. CONSTRUCTION: • Porous silicon chip • One side: etched to make hydrophobic • Other side: hydrophilic • Break chip using vibrations like ultrasound

  6. Construction contd. • When added to water, dust aligns with –phylic side • When oil droplets enter the pores of -phobic side, color changes • Degree of color change depends on identity of insoluble substance

  7. S-dust around hydrophobic liquid in water

  8. OPERATION OF MOTE: • Run by microcontroller • Determines tasks of mote • Controls power to conserve energy • Volume: key constraint • Batteries / Solar cells • Gets reading from sensor periodically • Optical receiver • Respond by CCR

  9. CCR • Corner cube retroreflector • Built using MEMS: Micro-Electro-Mechanical Systems • Placing 3 mirrors at right angles to each other to form corner of box which has been silvered inside • Reflects light back to sending position • By modulating position of mirrors, beams can be modulated

  10. APPLICATIONS: • Defense-related sensor networks • Dangerous for human • Virtual keyboards • Accelerometers • with a MEMS augmented-reality heads-up display, invisible computer I/O • Product quality monitoring • temperature, humidity monitoring of meat, produce, dairy products • impact, vibration, temp monitoring of consumer electronics

  11. Applications contd. • Smart office spaces • environmental conditions are tailored to the desires of every individual • Interfaces for the Disabled • to monitor blinking & facial twitches - and send them as commands • Inventory Control

  12. ON THE DARKER SIDE: PRIVACY????????

  13. CONCLUSION: It’s the power of PC, in a speck of dust.
