Engineering Goal
To build a complex system in a tiny volume.
This will be achieved through the progress of MEMS
Ultimate Outcome

• Small sensors
• Optical communication devices
• Power Supplies

Design Challenges
Energy Consumption Because of the small volume
of the mote, energy management is a key factor to
consider in the design of smart dust
Technologies used

• Batteries providing 1J/mm3
• Solar cells storing energy on capacitor
• Capacitors storing approximately 10mJ/mm3

7
Operation of the Mote
Because of the energy constraint, the part of the
dust must be powered on only when necessary.
Therefore the dust is controlled with a clock and
a few timers
Some timers control the sensors that measure
stimuli
Once a timer expires

• Powers up the sensor
• Sample is taken
• Analysis of the data

8
Operation of the Mote
Other timers are used to control the receiver
Once a timer expires

• Powers up the receiver
• Looks for an incoming packet
• Analysis of the data
• A message can be sent using a laser diode

Remote programming allows to send new
instructions to the individuals mote

Final Word
Smart Dust does not exist COTS Dust
Smart Dust will be able to sense, communicate and
be self-powered
5 millimeter mote
Expected 1-2 millimeter mote
