Smart dust

  1. 1. SMART DUST BY A SATYA KARTHIK 10071A0501
  2. 2. CONTENTS         INTRODUCTION MEMS TECHNOLOGY WHAT IS A MOTE? COMMUNICATION APPLICATIONS FUTURE OF SMART DUST CHALLENGES CONCLUSION
  3. 3. INTRODUCTION  Tiny electronic devices designed to capture mountains of information about their surroundings while literally floating on air
  4. 4. THE MEMS TECHNOLOGY  MEMS is the integration of mechanical elements, sensors, actuators and electronics on a common silicon substrate through micro fabrication technology
  5. 5. MOTES MOTES Tiny sensors that can perform a variety of functions
  6. 6. OPERATION OF A MOTE
  7. 7. SMART DUST SYSTEM REQUIREMENTS    Power Sensor Communication
  8. 8. COMMUNICATION TECHNIQUE   a) b) Wireless communication collects data from thousands of sensors simultaneously Various techniques are Radio Frequency Transmission Optical Transmission Technique
  9. 9. RF TECHNIQUE   Based on the generation, propagation and detection of electromagnetic waves Used to function as both the uplink and the downlink
  10. 10. OPTICAL TRANSMISSION TECHNIQUE   Free space optic communication a) Active Optical Communication b) Passive Optical Communication Fiber optic communication
  11. 11. APPLICATIONS Civil and military applications
  12. 12. VIRTUAL KEYPAD
  13. 13. BRIDGES SKYWRAPPERS
  14. 14. EFFICIENT MEDICAL IMPLANTS
  15. 15. Wearing temperature, humidity and environmental comfort sensors sewn into our clothes.
  16. 16. FUTURE OF SMART DUST   Number of research institutions The future of smart dust lies on both optical communication and fiberoptic communication.
  17. 17. CHALLENGES    To incorporate all these functions while maintaining a low power consumption Maximizing operating life given the limited volume for energy storage The motes must operate efficiently and conserve energy whenever possible
  18. 18. CONCLUSION Ongoing researches on Smart Dust Smart Dust mote : As small as possible Make it available at low price as possible.
