Touch Sensitive Bionic Hand

Innovated in early 2013 by the Italian bionic company Prensilia this bionic hand has the ability to allow the recipient to feel sensations similar to the natural sense of touch. Recently invented bionic limbs can receive brain signals that operate in emulation of an absent natural hand yet could not provide sensory feedback to the user. Prensilia bionic hand attaches directly to the bodies central nervous system by electrodes bound on the arm’s main nerve endings this enables amputees to have a restored sense of touch.

The connected electrodes allow the users to operate the hand with their thoughts and brain signals as they would with a natural hand, scientists are eager to improve the design of this bionic hand model thus begin a new generation of artificial limbs by increasing the dexterity and element of feeling. Amputees are often reluctant or uncomfortable to use artificial limbs due to the possibility of scrutiny and unreliability the limb as the design improves it may change public opinion as the technology becomes more similar to a natural human hand. The functionality of the hand is quite similar to how the brain controls an organic hand when a person moves their limb signals from the brain to the hand through nerves these are then interpreted by a small computer inside the bionic hand and processed into movement which activates the motors.

Dr Silvestro Micera, of the Swiss-based Ecole Polytechnique Federale de Lausanne, who helped develop the limb’s interface, said: ‘This is real hope for amputees. It will be the first prosthetic that will provide real-time sensory feedback for grasping.

‘It is clear that the more sensory feeling an amputee has, the more likely they will get full acceptance of that limb. We hope that one day it will be embedded in the arm and the user will just forget it is there.’
