Imagine a world where you are surrounded by the masses of smart particles at the nanoscale. This smart particles are a series of wireless sensors that gather various information about the world, and transmit it to the control center.

Each of these particles contain one or more sensors, a wireless telecommunications system, a rechargeable energy source which is augmented by the radio waves and an identification code (for fixed particles) or a GPS system (for moving particles). Such a structure is called Smart Dust. Consider, for example, smart dust that spread across the highway and transmit a variety of information such as light intensity and traffic to the control center. By Benefiting from this system, electricity utilities can quickly identify a faulty bulb and replace it. Or light density over road can be set depending on traffic.

As another example, smart sensors, which are scattered in a huge multi-storey car park can detect empty parking and send information to the control center. So, each car can be led to nearest empty parking by turning on pilot LED lights.

Or smart dust that spread over a bridge, can transmit oxidation rate, PH of water, corrosion rate and … to the control center.

Such a world is called a smart dust based world. In this world, doctors can control performance of critical parts of patient’s bodies by prescription of breathing or drinking the air or water which contains smart dust. This technology is the start of a new era of human control over the surroundings and an unlimited number of ideas to facilitate human life. Facilities that one day humans will be difficult to imagine life without it.
