A prosthetic hand called smart hand is being developed by researchers in Italy and Sweden, which allows the patients to have feelings in the fingertips.
The smart hand was tested on some patient, where it had four motors and forty sensors linked directly to the brain. They had surgery to have the patients’ nerve endings linked up to receptors in the prosthetic hand, enabling the patients to have feelings in figertips of the hand, even though it is not really part of the body.
The smart hand is the first of its kind that sends signal back to brain. It has taken the researchers 10 years of hard work, and finally they have one that at least allows those who’ve lost their hands to regain little sense of touch.
Of course, don’t compare with the real or biological hand made by God, as it has over millions of nerves in it, which current human technology can’t achieve with such a superb precision in this decade. Maybe, next decade they could probably have something closer.
