The latest technology creates the mind-controlled artificial limbs

Scientists and engineers managed to achieve significant progress in the world of prosthetics, by creating artificial limbs that can be controlled by the wearer's brain. Thanks to advanced sensors capable of picking up signals from the brain, an amputee Iceland citizen showing those technology can be used successfully.

"It took me about 10 minutes to learn to control this prosthetic leg, then I could stand up and walk," he said. Olafsson said it was like moving his leg muscles themselves. Last year, the sensors are very small, which was developed by the Alfred Mann Foundation implanted to the rest of the muscle tissue into the lower part of his right leg amputated ten years ago.

Thorvaldur Ingvarsson, an orthopedic surgeon who did the operation said, "We installed sensors in the muscles, which will capture the signal from the brain and distribute it to the prosthetic leg, so that the prosthetic leg was moving as ordered by the brain."

Sensors embedded in the muscle tissue as it has been used before, but Ingvarsson says this is the first time the amputated people could move the bionic legs without the need to focus intensively on the task.

Olafsson said that with practice, he is getting good at controlling the artificial leg. "Every day I learn more about how to run well, up and down hills, up and down stairs, even sitting and rising from a chair," he said.
Other orthopedic patients in Iceland also got the same result, while three patients in Austria earlier this year began using the same technology to control their bionic hand. The researchers say the next step is to develop a bionic organ that can make users really feel what they touch. *** [EKA | FROM VARIOUS SOURCES | VOA NEWS]
