Scientists have created a bionic hand which allows the amputee to feel lifelike sensations from their fingers.
A Danish man received the hand, which was connected to nerves in his upper arm, following surgery in Italy. Dennis Aabo, who lost his left hand in a firework accident nearly a decade ago, said the hand was "amazing".
In laboratory tests he was able to tell the shape and stiffness of objects he picked up, even when blindfolded.
The details were published in the journal Science Translational Medicine.
Implant. An international team carried out the research project, which included robotics experts from Italy, Switzerland and Germany.
The scientific advance here was not the hand itself, but the electronics and software that enabled it to give sensory feedback to the brain.
Micera and his team added sensors to the artificial hand which could detect and measure information about touch. Using computer algorithms, the scientists transformed the electrical signals they emitted into an impulse that sensory nerves could interpret.
