In the not too distant future, it may be safely used machines molecular size (ie extremely small) for what would be important control mechanisms of the human body such as the heart.
According to the results of an experiment conducted by scientists at the University of California, Berkeley, USA in conjunction with the University of Umea in Sweden, have shown the world how a nanoglobo, consisting of a single molecule of carbon, which is about ten thousand times thinner than the thickness of a human hair any, it can be perfectly controlled in order to electrostatically switched between an inflated condition and a deflated state.

The devices in the form of inflatable balloons are frequently used for what would macroscopic applications such as erecting buildings, impact protection in cars, or also to widen arteries or veins that have clogged. Regarding the micrometer scale, they are used as micropumps.
The shape of inflatable balloon of these "actuators" are unknown theory. But nevertheless, several years as some important researchers at Pennsylvania State University in the United States managed to devise an actuator in the form of nanoglobo, which was controlled by means of electrostatic charges, based on the "inflated" and "deflation" of a carbon nanotube fact.
Now this "theoretical" design was recently implemented in a research and experimental production that was made by Hamid Reza Barzegar. This team has shown the whole world how a nanotube tiny carbon made (which we can imagine as a very, very tiny cylindrical tube of carbon atoms), can be controlled by static electricity to be transformed from a state deflated to another inflation and vice versa with only a small voltage applied to it.
Thanks to what would be the free nature of defects that have the famous carbon nanotubes means that this actuator in question would be able to function without showing any wear nor any structural fatigue. In fact, the latter is further supported by extensive tests conducted by the researchers responsible for this innovation, evidence which was operated at a fairly unique variety of many devices over several cycles over and over again, without register any sign loss of performance or any wear.
