Denis Aabo Sørensen lost his left hand nine years ago, while handling fireworks. Since then, he has used prosthetic hands, but never one like this. Last year, a team of European engineers created for him a prosthetic hand that connects directly to the remaining nerves in his upper arm. That means the hand is able to send sensations of touch back through his arm and into his brain. Plus, when Sørensen wanted to grab something, he could move the hand by simply thinking about it.
"The sensory feedback was incredible," Sørensen said in a statement. "When I held an object, I could feel if it was soft or hard, round or square."
"I could feel things that I hadn't been able to feel in over nine years," he said.
