Smart Dust

...You go to a hospital and implant a vaccine, after this time regularly certain information about your breath health are sent to your doctor and he can predict the time of your breath cancer and cure it.
...In the middle night one silent aeroplane flyes over the war land and sprinkle a thick dust all over the land. From next morning all the tiny movements of the soldiers are sent to you and you can get the control of the war.

These are not some pictures of scientific-fiction Hollywood films ,but they are the usages of the new technology which is called Smart Dust. With the advent of these intelligent articles you have lots of micro sensors which are able to sense temperature,humidity, pressure, light intensity, smell, speed, acceleration, direction, height, vibration and lots of more signals which could be useful about the training object.
Maybe in less than 10 years using Smart Dust will be public and then we can benefide another feature of modern technology.
I just liked reading this text so I translate some parts of it from Zigzag magazine for you.
