Microelectronics Advanced signal processing is really reaching the dream of bringing to the reality the fusion between mankind and machine. In these artificial systems, the flow of information is done through data cables, and in some cases, by means of radio links, and the equivalent process of communication occurs to living beings, but the transfer takes place through the nerves. The two systems are connected through simple devices such as keyboard, mouse, touch screens, which will become more sophisticated and increasing its complexity, as the example of neuromuscular electrical stimulation that causes functional movements or the so-called sensory prostheses, used to restore loss of some organ.
