For The First Time a Male Quadriplegic Regains The Sense of Touch Technology

It is a reality that advances in prosthesis and mechanisms for paralyzed people with lack of any member or have evolved a way to incredible, reaching robotic devices and even those that rely on 3D printing. But there is still a pending task, which is trying to recover the sense of touch.

We have already seen a couple of projects focused on synthetic fur and sensors in prosthetic that precisely seek to get people to feel, but today is has unveiled a new milestone in this segment to have achieved that for the first time a quadriplegic man feel through a bionic hand.

Not only is substitute member, but recover all its functions

A group of researchers and physicians at the Center for the neural basis of cognition in Pittsburgh, Pennsylvania, have achieved that Nathan Copeland, a 28-year-old quadriplegic, again having the sensation of touch through a hand bionics, thanks to some brain implants.

In ancient developments based on brain implants already had managed to move the fingers of the prosthesis as well as the application of different levels of force with only the thought, but now in addition to move them it will be possible When one finger touches or is touched an object or surface.

This work is an extension of the research of brain implants in the motor cortex than now expands to the somatosensory cortex, It is the part of the brain that registers the sense of touch. The work consists of the implantation of electrodes in the brain that are linked with the robotic hand through a computer.

This is the first time that is achieved that a people paralysed from the neck down to move a robotic hand and at the same time makes sense of touch fingers with an accuracy of 80%. The next step of this project will be to extend the reach of the brain implants to control Prosthetics in both hands and legs and feet.
