Dennis
amputee, Aabo in February 2014 became the first person to receive a bionic
hand, which allows life-like sensation to be felt from the device’s artificial
fingers.
The Dennis amputee was able to feel what was available in his
hands by the sensors, which has been connected to his nerves of his upper arm. This
work was done by the Italy surgeons, who connected the hand with the
nerves in his upper arm. These relayed signals direct to his brain,
which allows him to control the force of his grip. Restoration of senses of
touch and feel to amputees is a major goal in the field of neuro-
engineering. Aabo lost his hand in a firework accident
about a decade before. The research project was carried out by an international
team, which included robotic experts from Germany, Switzerland and Italy.
The
sensors to the artificial hand sensed the measure information about touch using
computer algorithms in which the research team of scientists transformed the
electrical signals they emitted into an impulse that sensory nerves could
interpret. The researchers implanted four electrodes onto the nerves in the
patients’ upper arm during the operation that were connected to the artificial
sensors in the fingers of the prosthetic hand, which allows him to touch and
pressure and sent feedback directly to the brain. Details of the operation of
the amputee were published in the journal Science Translational Medicine.
