Smart dust The giant of the future. A threat to privacy

Intelligent Dust: A Virtual System Of MicroElectroMechanical Systems (MEMS) Of Wireless Models, Robots And Dust Materials Operating Within Connected Networks (Network) That It Can Capture Information Carried By Light, Heat, Sound, Vibrations, Wave Signals, Electric Or Magnetic Field, Or Chemicals. Research and experiments in this area revolve around wirelessly netting these dust robots and spraying them over specific areas in order to perform sensing or spying tasks.

 

These dust systems can track visitors’ movements as they move into their coverage field. It can also implement other applications such as identifying hazard points and lines in building structures after an earthquake, for example, warning of the presence of biochemical toxins and may be programmed to perform the GPS mission of positioning a military site or perhaps an entire city.

Warnings about the future of smart dust:

Such dust sensors can send important information such as the nature of air, heat, humidity, light and vibrations and this is only the beginning. This technological innovation can be described as mobile smart cloud forms that can be programmed to be automated or remotely controlled and employed. One of its supposed functions is also to explore accessible planetary spaces, modify the temperature of the Earth’s atmosphere, sensing earthquakes, tracking enemy soldiers or mechanisms, and other applications at the heart of social life.

 

The promises of smart dust are almost incredible and frightening at the same time. A few years ago, when the smart dust unit the size of a sulfur stick, successfully tested its functions of measuring the speed of cars and land vibrations on a road in California after being thrown from the plane on the sides of the road and began broadcasting information as programmed.

 

A research project is underway deploying hundreds of sensors covering eastern California. The project aims to measure the speed of continental encroachment of the American continent and develop the study of volcanoes, mineral deposits and earthquakes. The project began by 2008 and will remain until 2023. (William Brod) Taking the Pulse of the Earth (The New York Times).

 

And it won’t be long before smart dust grains can capture people’s movements and locations. It will no longer be difficult to imagine that intelligent dust will be scattered on people’s hair and program it so that it recognizes and transmits the type of DNA gene of the host person in addition to its location and perhaps his speech!!

 

This cloud can move with the wind and its shape and characteristics can be changed by exposing it to an electric or magnetic field. Smart dust grains can communicate with each other and assemble in the cloud of the cloud of a dense bee. Even as wind blows, these tiny creations can be controlled and directed in any direction in order to get them to their goals.

 

One typical application is to scatter hundreds of these sensors around buildings or hospitals to monitor heat or humidity, track patient movements, and inform disasters such as earthquakes. They can be used in the military as remote sensing chips to track enemy movements and detect toxic gases or radioactive materials.

 

Smart dust, for example, will be able to monitor the temperature inside computer data centers and supply the data control system in order to adjust the cooling level according to the data received, saving a lot of wasted energy and maintenance cost.

 

Science fiction or project in progress?:

It may seem like we’re in front of a science fiction story so far. The modern idea of smart dust originated from science fiction writers such as Neil Stefansson and Werner Feng in the early 1990s, but the story began decades earlier when a similar topic appeared in 1964 in a science fiction book called Invincible.

 

The term “smart dust” was coined in 1997 by American scientist Chris Pister, a professor of electrical engineering at the University of California, Berkeley and co-founder and president of Dust Networks. In 1994, he began work on a project to build a network of miniature sensors of no more than one cubic millimeter. The sensor may not exceed one cubic millimeter capable of detecting minor changes in light, vibrations, and air acceleration, and these sensors, called the atom of dust, may communicate wirelessly via radio waves, powered by solar energy and one centimeter in size. Bester and his team, backed by the Defense Advanced Research Projects Agency (DARPA) of the US Department of Defense, have not yet reached this big goal, but they have come close to it, they have been able to build a wireless sensor less than 5 centimeters in size, the size of a grain of rice. Bister says that each sensor works completely independently, can make two-way connections and send up to 100 meters.

 

When smart dust is distributed in the right places, it shows magical effects. If it is equipped to monitor the signals and movement of the human body, then he can alert doctors and nurses to changes in the patient’s condition. If he is prepared to read water levels and chemicals, he can alert farmers to the problems facing crop growth, and he can improve heating and cooling systems in buildings by monitoring heat and airflow.

Sensor technology is already used in many fields, but smart dust is theoretically smaller and cheaper than wired devices used today. Buster says that the cost of one sensor used in air conditioning systems currently ranges from $500 to $1,000, and most sensors are connected by wires, and there must be manpower to install them, while in the case of smart dust, more sensors can One form of this technology has already reached the market, as Dust Networks, headed by Bester, is currently producing models of smart dust for factories and heating and cooling systems, but the only problem with the commercially available sensors today is that they are not really like dust. The size of this company’s sensors reaches the size of a sulfur can, Which is related to the size of its batteries, Bar-Bester sensors can work for five years with a pair of AA batteries and scientists expect the size of these sensors to diminish over the few years, bringing wide applications in all fields, especially medicine, industry and military fields.

 

This project was selected for funding by the university in 1998. But the development and follow-up of the Smart Dust Project has found significant support in military technology applications. In his recent research publication, researchers, including Christopher Bister, discuss various techniques for the use of smart dust in a network of sensors of less than one cubic millimeter each, and even talk about the possibility of making it a micrometer (a thousand times smaller), especially as advances in silicon processing, material physics and nanotechnology promise to reduce the size of sensors to the level of Sand grain and its programming based on its mechanical, physical, chemical, photochemical and electromagnetic properties.

 

Many researchers and research institutes are dealing with the subject, including Dr. John Parker of the University of Glasgow, Dr. John Barker (Glasgow), a principal investigator at the Research Center specializing in high-speed systems, one of the founding members of a wide range of international companies, and has developed a similar concept to smart dust called “smart spots.”

It is still at the beginning of the experimental phase, but this technology seems promising in terms of space exploration, especially the expansion of the recognition of Mars. In addition, its supposed applications in the Earth’s environment seem unlimited.

While the research community is preoccupied with what will leave the PC, the topic of wireless sensor networks has become a new environment that poses new challenges and prospects for researchers.

Three technological keys were behind making this environment available. Electronic-digital circuits, wireless communications, and micromechanical systems (MEMS). In each of these fields advances in hardware technology and design engineering have reduced volumes, reduced cost and reduced energy consumption.

This allowed the emergence of complexes of low-sized independent sensors; each containing multiple sensors as well as capabilities in programming, communication and energy feeding.

 

About a year ago the size of the smart dust grain was still around 2 cubic millimeters. Last year at the Intel Research Laboratory in Berkeley, researchers tested a small, intelligent dust-speaker system they called SPC that was equipped and programmed to send radio signals at 902 MHz for 13 meters at 13,200 kbits per second. In this broadcast, the system consumed a thousand times less energy than any cellular device.

Today, researchers have been able to reduce the smart dust grain to 1 cubic millimeter where it can contain models, software circuits and wireless communication technology from transmitting, receiving and the possibility of producing energy independently. In some tests, smart dust could be used with 350 meters of radio transmission-reception coverage between systems that exchanged all types of data and software applications. Some have served their batteries for more than 5 years and some can use renewable energy from the sun, air traffic or radioactive materials. Here, mention should be made of the concavings resulting from the arrival of radioactive, charged or programmed intelligent dust to its main destination and the resulting complications that may not count results.

Certainly, a mind with a broad imagination can take smart dust applications into very cool or very intimidated uses. But one thing is certain: smart dust technology is making its way in academic and military research laboratories towards greater complexity and sophistication and it seems that no one (governments or scientific institutions) can rein in smart dust. This genie has left its bottle and every grain of this dust is worth its weights gold.

In early 2001, the Journal of Rigid Physics, published by the Institute of Electrical and Electronic Engineering, published the results of a research project carried out by a team of scientists in the Department of Electrical Engineering at the University of Florida, during which a fully constructed wireless communication system was reached on one of the microelectronic chips used in the computer industry, measuring an area of millimeters. This system consists of a precise radio wave transmitter, a microwave antenna that is barely visible to the naked eye and a precision transceiver unit of the same size. This development was an announcement of the possibility of building the integrated wireless communication infrastructure necessary to achieve effective communication between each smart dust grain and another.

In 2002, the concept of lasky sensor networks appeared and began to be applied in some islands to monitor the movement of birds and in some agricultural and other applications. In 2005, an electronic chip was developed in which sensors are integrated with information transmission tools on one silicone chip with a diameter of 5 millimeters. Scientists then completed the rest of the components of the chip, such as conductor, antenna and an unconventional source of power sensor such as solar cells such as the movement of windows or tree branches to which dust atoms adhere.

Then special research emerged to integrate smart dust technology with mobile phones. Then he started talking about a project within the US space agency NASA aimed at reconfiguring smart dust to work with web technology used online to allow for a wide sharing of information collected by dust atoms in the sense of creating information networks powered by Internet technology through which smart dust granules are linked to the way computers and websites are linked, and with its capabilities and high flexibility in collecting information from thousands of grains, collecting and processing it centrally and then making it available for participation. Then the matter developed and starting to talk about dust atoms that see and hear, that is, equipped with cameras that take pictures and microphones that capture sound and then transmit what they visualize and hear through wireless networks to the collection center.
