What they will be, computers of the future ? The next generation of computers will be able to perform many more operations, and their sizes are reduced to a speck of dust.

Tiny computers that have received in the scientific community called “smart dust”, will not differ from their older counterparts nothing but size. They will continue to work on the basis of miniaturized processors running a standard operating system with access to the same small modules of RAM and flash memory. In the future, these microcomputers hundreds, and perhaps even thousands, will be integrated into buildings and other objects around us, writes science magazine New Scientist.

His first prototypes of “smart dust” scientists in the University of Michigan Ann Arbor (USA) was named Michigan Micro Motes . Device the size of a cubic millimeter of air temperature control sensors and movements that convey information on the radio.

How to charge some tiny computers? World covered with “smart dust”, it is certainly interesting, but there is one small problem, which is the need for sensors with enough energy, said Joshua Smith, head of the Laboratory of Sensory Systems at the University of Washington in Seattle (USA).

Like Robinson Crusoe microscopic, specks will be supplied with energy from the environment. Sensor near the light source can use a tiny solar panel , while the other sensors under different conditions – generate electricity by temperature difference .

Micro Motes can be used to track the movement of large man-made structures such as bridges and skyscrapers . In the “smart” house “smart dust” will be able to control the lighting , temperature, level of carbon dioxide emitted from fossil fuel combustion, as well as to report on the number of people in the room. Sensors built into your personal stuff, never ever lost. Determine their current location in the real world will be using search Google.

Tiny computers can be used for medical purposes. Chips implanted in the body, will collect information on the main indicators of the state of the patient. Researchers at Michigan State University have conducted successful tests on implantation Micro Mote in the tumor tissue of laboratory mice to monitor the development of the tumor.

Smith is also a researcher working on a miniature computing platforms WISP, that communicate via radio frequency identification device. Just as Micro Motes, sensory WISP not need a battery, as feed electromagnetic field energy, the source of which serves, for example, tower.

But the main problem that should be solved in the course of computer miniaturization – is the transfer of data. The amount of energy that is spent to perform Mote 100,000 computing operations are only sufficient to transmit one bit of information to the outside world, said research team leader Prabal Dutta.

Meanwhile, scientists at the California Institute of Technology closer to a perpetual electronic chips .
