University Work

Topic has naming: the work is replaced by electric motor muscles. It would like to tell about this new and innovative development of scientists, as an artificial electrical muscle. Those who are familiar with electrician and the basics of electricity, is well aware of the basic ways of converting electrical energy into mechanical motion. This is, first of all, electric motors of various types, principles of operation, type of power, etc. They have, by passing electric current through the inner windings, formed the electromagnetic fields to repel each other, thereby causing the rotation of moving parts. Such movements have rotational in nature, which often requires additional mechanisms for the conversion of translational. At the same time lost some of the energy, increasing energy costs.

Even the motors because of their construction and operating principle of efficiency is not ideal. There is another way to make forward movements by means of the same magnetic field. This is a retraction or repulsion in the electromagnet core. Disadvantages is also not ideal efficiency and the difficulty of a precise control of the action. Now let's see what can be replaced by an electromagnet and electric motor work in our time. This is an analogue human muscle, which runs on the same principle. As you should know from the lessons of biology, upon the momentum of the human nervous system to its muscles, there is a reduction of protein fibers. This eventually leads to simple muscle contractions (reduced length) and carry out some physical work.

This principle is very simple. But due to the fact that scientists are a long time could not create such an artificial material that would repeat the work of human muscles, this idea was in place and had no further development. In 2007, scientists from the University of North Carolina, announced that they have managed to create such an electrically conductive polymer on based on carbon nanotubes.
