Bionic arm gives the feeling of touch
A woman was able to feel her arm after losing it 25 years ago in an accident.
This has been made possible by the scientists who have created a portable bionic hand.
The hand has been created with a technology that can imitate the sense of touch and the person gets the sensation of actually touching something.
The prosthetic hand has sensors that can detect whether an object is soft or hard.
The computer-processed information is relayed to the brain with the help of electrodes that are implanted in the upper arm.
The electrodes convert the sensor information into signals that can be understood by the brain.
When the bionic arm touches or holds something the brain gets the relevant signals and produces the sensation of touch.
The recipient of the arm Almerina Mascarello has said that she felt like it was her real arm and not a prosthetic.
