The perception of the environment and the command of the movement suppose
communications within a network, and in this case a network of nerve cells called
neurons. According to Wikipedia this unique cell which is the neuron maybe defined
as a unity of the nervous system specialized in the communication and the processing
of information. With this definition we can assert that this cell has a leading part to
make circulate the information between the environment and the body and vice versa.
Let us note that this communication is based on the travel of the electric signals, the
characteristics of which are the following: amplitude situated between] 70 mv; 30 mv
[with duration about 5 milliseconds. From this point of view we have just presented in
a summary way the role played by that cell is in our body. Finding solutions for the
disabled persons is a major challenge for our society. In the case of a disability due to
a malfunction of the nervous system, the origin may be accidental, genetic, or induced
by environmental factors. This type of anomaly can cause loss or movement disorders
(paraplegia, hemiplegia, quadriplegia, epilepsy, Parkinson's disease, multiple sclerosis,
etc.) or malfunction of certain sensory functions (blindness, deafness, chronic pain,
etc...). Many alternatives, more technology, include creating interfaces between the
human body and an artificial prosthesis to restore some functions of the human body
have been proposed. A wireless system and no battery neurons probe was developed
in this work for reading and stimulate the neural signals in the brain using a surface
acoustic wave one ports (SAW) delay line reflection.
