Smart dust is a system of many tiny micro-electromechanical systems such as sensors, robots, or other devices, that can detect, for example, light, temperature, vibration, magnetism, or chemicals.

There are nodes in smart dust system which are called Motes.

Smart Dust – An Introduction

Dust word is used to show similarity of small size dirt or sand to the particles that have brain.Smart dust sensors are relatively small and portable.Smart dust sensors are battery powered and can communicate wirelessly with the internet and with other sensors.

Smart Dust in real world

• Accelerometer containing smart dust

• MEMS microphones in portable devices

• Monitor speed and volume of traffic to avoid recurring traffic jams.

IT Sector

• The motes used for defense purpose consists of magnetometer, a vibration sensor and a GPS receiver.

• Spread on the battlefield by moving vehicles or soldiers with modified binoculars.

• used to monitor critical part of aircraft.

Defense Application

• Enter human bodies and check for physiological problem.

• relay information about cancerous cells.

• Artificial retina

Medical Application

• In Environment conservation• Detects hazardous chemicals

and biological agents.• Monitoring nature of animals.• Measuring temperature,

humidity etc.

Environmental monitoring

1. Relatively high power consumption.2. Hence can be used only for a short duration of time.3. Components like active beam-steering mechanism makes the

design of the dust mote more complicated.4. It is difficult to fit all the particles into small smart dust both in terms

of size and energy.5. With devices so small, batteries used present massive addition of

weight into it.

Disadvantages

1. Smart dust is receiving huge investment around the world and it could be used to create safer and more efficient food and agriculture system.2. Smart dust’s development, use, and employment in the future, further research is necessary.3. It can help in save a lot of loss of power in light and climatic control

building.
