Bionic hand allows human to "feel” real size, texture and shape of objects
First patient to test a sensory-enhanced prosthetic hand, which allowed him to “feel” the size, shape and texture of objects.
A man has
become the first amputee to have a “lifelike” sense of touch restored to his
lost limb in an advance that blurs the boundaries between human and machine.
Dennis Aabo
Sorensen, a 36-year old property developer from Denmark, lost his left hand 10 years
ago when a accident firework went off as he was about to light it during New
Year’s Eve celebrations, said the hand was “amazing”.
"I
didn't realize it was possible," said Dennis Aabo Sorensen from Denmark,
who underwent the implant surgery in Italy and spent a month in a lab
describing his experiences with the novel prosthetic to an international team
of scientists. "The feeling is very close to the sensation you get when
you touch things with your normal hand."
The
developers are yet to establish how well the electrodes will keep without
deterioration in the long run, although Sorensen’s result was promising and
gives hope that the electrodes will function for several years without causing
harm.
There is
also an issue of miniaturization. All the equipment and cabling would have to
fit inside a prosthesis to be practical.
