Igor Spetic’s hand was in a fist when it was severed by a forging hammer three years ago as he made an aluminum jet part at his job. For months afterward, he felt a phantom limb still clenched and throbbing with pain. “Some days it felt just like it did when it got injured,” he recalls.
Igor Spetic lost his hand in a workplace accident. Now he’s one of the first people ever to regain realistic finger sensations thanks to nerve interfaces (below) implanted in the arm.
He soon got a prosthesis. But for amputees like Spetic, these are more tools than limbs. Because the prosthetics can’t convey sensations, people wearing them can’t feel when they have dropped or crushed something.
