Science: A More Natural Robotic Hand

"Italian researchers on Thursday unveiled a new robotic hand they say allows users to grip objects more naturally and features a design that will lower the price significantly.

The Hennes robotic hand has a simpler mechanical design compared with other such myoelectric prosthetics, characterized by sensors that react to electrical signals from the brain to the muscles, said researcher Lorenzo De Michieli. He helped develop the hand in a lab backed by the Italian Institute of Technology and the INAIL state workers' compensation prosthetic centre."

Not quite this but it'll do.
