The artificial hand gives the feeling of touch Science

The United States

Cleveland Clinic researchers say they have developed an artificial hand that can be used to feel the touch of the fingers.

Users of traditional moving hand prostheses have to keep a close eye on their hand to see how much force is needed to hold different items, such as a water glass.

A new type of prosthesis transmits information about the sensitivity of touch to the brain through nerves, researchers tell Reuters.

In practice, the movement of the artificial hand is successful by thinking about the movement, i.e. in the same way as the right hand. In the tests, however, the movement of the hand has been aided by various additional sensors.

“We built the system using a standard prosthesis as a base. Then we added advanced information technology to it: touch and motion detection, ”explains the

The researchers praise the subjects were able to perform tasks using the prosthesis in the same way as with the right hand.

“The user feels like their hands are moving even when they don’t have a hand. Their brains think the hand is part of the human being, ”says Marasco, who has been working on the project for a decade.

It is not yet known when the invention can be made available to the public. The development of the prosthesis continues.
