It await like the next propagation of prosthetic limb is upon us . Later this year , a patient living in Rome will receive an advanced prosthetic hand with centripetal capacities . The handwriting will be telegraph directly to the man ’s nervous system with electrodes , earmark him to moderate its drift — and to pick up spot signals from the bridge player ’s skin sensors .
reckon being able to pick up an object , but not being able to find its grain , temperature , or shape . It ’s this lack of outside feedback that has frustrated prosthetic researchers for year , but with this young hand , it come out they ’re inching closer to something that more closely gauge a human hand .
To make it work , the hand ’s electrodes will be dress onto two of the arm ’s primary boldness , the median value and the ulnar nervus . It will form a cybernetic connection let for the fast and bidirectional flow of information between the patient ’s nervous system and the artificial hand .
harmonise to its developer , Silvestro Micera of the Ecole Polytechnique Federale de Lausanne in Switzerland , it ’s the first prosthetic that will provide real - time sensory feedback for prehension . Micera made the annunciation at the recently concluded AAAS league in Boston . He added that increased sensational feelings will improve sufferance of artificial limbs among patients .
The new hand is an update variant of one that was grow in 2009 .
The Independentexplains :
An to begin with , portable model of the hand was temporarily bond to Pierpaolo Petruzziello in 2009 , who lose half his arm in a railroad car accident . He was able to move the bionic bridge player ’s fingers , clinch them into a fist and harbor objects . He said that he could feel the aesthesis of needles pricked into the hand ’s palm .
However , this earlier version of the hand had only two sensational zones whereas the latest image will post sensory signal back from all the fingertips , as well as the palm and the wrists to give a near life - like feeling in the limb , Dr Micera say .
“ The idea would be that it could deliver two or more sensations . You could have a catch and receive information from three fingers , or feel motion in the hand and radiocarpal joint , ” Dr Micera said .
“ We have refined the port [ relate the script to the patient ] , so we hope to see much more elaborated bowel movement and control of the hand , ” he told the encounter .
The patient will wear the new helping hand for a month , and then be re - evaluate . Micera is hoping to develop a lasting , full - working framework within two years .
