Students Create Thought-Controlled Prosthetic Arm

Zothecula writes "Two undergraduate students from Toronto's Ryerson University have created a prosthetic arm that is controlled by its wearer's brain signals, and powered by compressed air. Not only is the Artificial Muscle-Operated (AMO) Arm said to offer a greater range of movement than traditional prostheses, but it also doesn't require the amputee to undergo invasive surgery, is easy to learn to use, and it is relatively inexpensive to make."

Hard to tell whether this is anything new or not when the article makes such glaring errors as:

While some traditional prosthetic arms move via myoelectric motors and relays

Myoelectrics involves sensing muscle movements by the electric fields generated, and is nothing to do with a type of electric motor. I doubt if anyone has used a relay in a prosthetic limb for at least a decade.
If they really just using an EEG headband to control the arm, it's going to have very low controlled dexterity, and extremely slow response.
