Four people in the United States have had this bionic-arm surgically attached. The arm is capable of sending touch sensations to the wearer, so that if a person is touched by another person's hand the wearer will feel the sensation. I would assume that the wearer would also be able to feel objects that the arm comes in contact with. The arm articulates elbow and finger movements based on impulses from the wearers brain. In plain English, if the wearer thinks about moving their elbow - the elbow will move.

The device was surgically implanted at the Neural Engineering Centre for Artificial Limbs at the Rehabilitation Institute of Chicago. They use a process called targeted muscle reinnervation, which involves removing certain nerves from the chest and re-purposing them for use in the prosthetic arm. This is accomplished by taking the nerve fibers from the chest and attaching them to the remaining nerves in the arm. Myoelectric-Sensors then detect nerve impulses that would go to the arm and articulate the prosthetic accordingly.
