Man Controls Cybernetic Hand With Thoughts

MaryBethP writes "Scientists in Italy announced Wednesday that Pierpaolo Petruzziello, a 26-year-old Italian who had lost his left forearm in a car accident, was successfully linked to an artificial limb that was controlled by electrodes implanted in his arm and connected to the median and ulnar nerves. He has learned to control the artificial limb with his mind. According to CNet, Petruzziello says he could feel sensations in it, as if the lost arm had grown back again. The BBC has a brief video showing the arm in operation."

Making something that can be affected by resistance - say, a hand touching the fake arm - shouldn't be difficult at all. While not entirely familiar with the technologies, something akin to touchscreen tech, the holographic stickers on old old old school Transformers toys, etc should be easily measurable.
