Smart dust are tiny wireless sensors that can detect things like light, temperature, and vibrations. They are called "motes" and contain sensors, computing circuits, wireless communication, and a power supply integrated into a dust-sized device. Smart dust motes relay sensor signals back to a central computer and are being researched for uses like monitoring environments, tracking objects, and circulating inside the human body to detect health issues. Challenges include reducing their size, weight, and power consumption to enable longer operation times.

1. Smart Dust(Tiny sensors)- The Little
Wonder

3. "Smart dust" devices are tiny wireless
microelectromechanical sensors (MEMS) that can
detect everything from light to vibrations.
Nodes in Smart Dust are called Motes.
These "motes" contain sensors, computing
circuits, bidirectional wireless communications
technology and a power supply integrated on a
tiny dust size-device.

4. For the next disruptive technology: think dust.
No, not small grains of sand, soot or dirt but
similarly sized particles that have a brain.
Transmits information like temperature,
humidity, light ,vibrations, surface pressures, etc.
Smart sensors relay signals back to a command
computer.
The motes' hardware platform uses
Processor(MPR). These are battery-powered
devices where MTS (sensors) and MDA (data card
sensors) work directly with the Mote Processor.

5. Smart Dust is a network of ‘motes’, identical or
similar tiny computers consisting of four
miniaturized components:
Ambient sensor
Wireless Transmitter
CPU
Power Source

6. Digital circuitry
MEMS technology
RF-Wireless Communication

8. Micro-Electro-Mechanical Systems (MEMS) is the
integration of mechanical elements, sensors,
actuators, and electronics on a common silicon
substrate.
While the electronics are fabricated using
integrated circuit (IC) the micro mechanical
components are fabricated using compatible
“micromachining” processes.

9. A wireless communication system is required
for sending and receiving data with data
transfer rate of 1 Kbps.
The devices for communication are subjected
to size and power constraints.
It must support bi-directional
communication between a central transceiver
and up to 1000 dust motes.

•Extremely low power

14. SMART DUST
Virtual Keyboard
• Accelerometer

• MEMS microphones in
portable devices
• Monitor speed and
Volume of traffic to avoid
recurring traffic jams.
• Also used in modern
cars for a large number
of purposes including
airbag deployment in
collisions.

15. • The motes used for
defense purpose of
consists of magnetometer,
a vibration sensor and a
GPS receiver.
• Spread on the battlefield
by moving vehicles or
soldiers with modified
binoculars.
• Also used to monitor
critical parts of aircrafts
and other war vehicles.

16. Circulatory Net
• Enter human bodies and check for physiological
problems.
• Relay information about cancerous cells.
•Doctors will be able to monitor health status and
curing situations of patients through smart dust.
•Surgery will be more and more efficient and
reliable as it will provide an extra arm for surgeons
in their daily duties.
• Biomedical application – Artificial Retina.

17. • In Environment
Conservation.
• Detect hazardous
chemical and
biological agents.
• Monitoring
nature of animals.
• Measuring
Temperature ,
humidity, etc.

18. • Relative high power consumption.
• Hence can be used only for a short
duration of time.
• Components like active beam-steering
mechanism makes the design of the dust
mote more complicated.
• It is difficult to fit all the components in a
small Smart dust both in terms of Size and
Energy.
•With devices so small, batteries used
present a massive addition of weight into it.

19. • ‘Smart dust’ is receiving huge investment around the
world and it could be used to create a safer and more
efficient food and agriculture system.
• Smart Dust’s development, use, and employment in the
future, further research is necessary, specifically in the
areas of intelligence analysis and dependence.
• Social aspects- it can help in saving a lot of loss of power
in light and climatic control of building.

20. • Large Scale Processing & Distribution.
• To bring multi-hop network topology.
• Data Fusion.
• Autonomous Network
Configuration.
• Researches on reducing
the size and weight of the
latest generation motes.
• Trying to make it so light that it flows on with
the direction of air.

21. Many ongoing researchers on the Smart
Dust Project are working on to make the
size of the present latest generation mote
as small as possible and to make it
available at a low price.
And then soon we will see Smart DustSmart Dust
