Artificial Neuralgia delivers life for prosthetic limbs

US scientists have successfully tested an artificial neuralgia, which is expected to help people with disabilities feel the heat and cold through artificial limbs.

Scientists have successfully tested the animals, which are expected to be available in the next 10 years. This is the result of research by Paul Cederna, professor of cosmetic surgery at the University of Michigan, USA.

Professor Cederna said that artificial neuralgia was made from a conductive polymer called Pedot, which can connect prosthetics with the brain effectively, a rate that is twice as fast as the neurons themselves. However, the electrical signaling power of the nervous system is 10 times higher than that of those using metallic materials.

New nerves help disabled people get the feeling of hot, cold collision from replacement parts such as the legs, the prosthesis.

' Their feelings are so real, and the brain does not have to repeat the second time, because the nerves have transmitted all the signals,' Cederna said. This artificial neuron is equipped with nano-sensing elements, which can distinguish contact, heat and other sensations. These sensors also help the user to feel the impact of external forces. This kind of sensor is still in the research stage.

Currently, the number of people with leg limb in the world is not small, in the UK about 5,000 people have to install artificial limbs.

John Butterworth, 23, a former British Air Force officer, lost his left arm during the Iraq war in 2007. When talking about the use of artificial limbs, he said: 'You do not feel about The pressure, when you hold a cup of coffee, you have to look at the prosthesis and be sure to hold the position of it. If you can use artificial hands, this is a miracle. '

Cederna hopes to start a clinical trial in three years, and may be able to put the technique into use in the next 10 years.

Michael Fox, a consultant at the Royal Thai Orthopedic Hospital (RNOH), said that the technique had to address some technical issues before it could be put into use. "When you want to go from brain prosthesis to brain, you have to be careful, if the brain receives the wrong signal it is extremely dangerous. It's too early to talk about this, " Michael Fox said.
