Amputee ‘feels again’ using a bionic hand
SCIENTISTS have developed the first ‘Star Wars- style’ sensory bionic hand that can be used outside of a laboratory.
Almerina Mascarello, 62, who lost her left hand in an accident in a factory, was fitted with the robotic device which can be controlled by her brain and can feel what it holds.
It allows her to carry out actions that pose great difficulties for amputees – such as getting dressed.
Mrs Mascarello says the device ‘is almost like [her hand] is back again’. In tests, the married mother of two was able to tell whether an object she picked up with the device was hard or soft while blindfolded.
She told the BBC that the hand, developed in Rome, allows her to carry out her hobby of fixing cars.
In 2014 the team produced the world’s first feeling bionic hand but it was too big to leave the laboratory. The latest version is portable and fits in a rucksack. The development team from Italy, Switzerland and Germany linked information from the hand’s sensors to a computer in a rucksack that converts signals into impulses the brain will understand.
Data is relayed to Mrs Mascarello’s brain via tiny electrodes in her arm’s nerves. She said: ‘The feeling is spontaneous as if it were your real hand.’
Professor Silvestro Micera, a of the Swiss Federal Institute of Technology in Lausanne said: ‘We are going more and more in the direction of science fiction movies like Luke Skywalker’s bionic hand in Star Wars.’
