Researchers in Italy and Switzerland have created a bionic hand that allows mutilated people to feel their fingers again.
The invention is at the stage of clinical testing. It was applied to the Danish Dennis Aabo, who accidentally lost his left hand from the elbow and down.
At essay, the 36-year-old patient was able to identify the hardness of the objects he was grasping while blindfolded.
“The hand has sensors attached to every tendon in every finger. And we can use them to understand the force exerted by the patient as he grasps an object. We use it information this in order to cause the exact stimulation of the sensory neurons and thus to restore this sensation in real time in the nervous system", explains the researcher Silvestro Micera.
Η device applied to the 36-year-old patient was temporary and surgically removed.
In order to create a permanent and viable prosthetic member, scientists will need to significantly reduce electronic components.
"The first time they set it up was amazing. Suddenly I began to feel things I could not for many years. I was able to understand the round and hard and soft objects, and it was a great feeling, "says 36Dan Dane.
Next challenge to the scientists, a bionic arm so advanced that it beats able-bodied people in bra-de-fer.
