CONTENTS         INTRODUCTION MEMS TECHNOLOGY WHAT IS A MOTE? COMMUNICATION APPLICATIONS FUTURE OF SMART DUST CHALLENGES CONCLUSION

INTRODUCTION  Tiny electronic devices designed to capture mountains of information about their surroundings while literally floating on air

THE MEMS TECHNOLOGY  MEMS is the integration of mechanical elements, sensors, actuators and electronics on a common silicon substrate through micro fabrication technology

MOTES MOTES Tiny sensors that can perform a variety of functions

OPERATION OF A MOTE

SMART DUST SYSTEM REQUIREMENTS    Power Sensor Communication

COMMUNICATION TECHNIQUE   a) b) Wireless communication collects data from thousands of sensors simultaneously Various techniques are Radio Frequency Transmission Optical Transmission Technique

RF TECHNIQUE   Based on the generation, propagation and detection of electromagnetic waves Used to function as both the uplink and the downlink

OPTICAL TRANSMISSION TECHNIQUE   Free space optic communication a) Active Optical Communication b) Passive Optical Communication Fiber optic communication

APPLICATIONS Civil and military applications

VIRTUAL KEYPAD

BRIDGES SKYWRAPPERS

EFFICIENT MEDICAL IMPLANTS

Wearing temperature, humidity and environmental comfort sensors sewn into our clothes.

FUTURE OF SMART DUST   Number of research institutions The future of smart dust lies on both optical communication and fiberoptic communication.

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

CONCLUSION Ongoing researches on Smart Dust Smart Dust mote : As small as possible Make it available at low price as possible.
