This prosthetic arm is powered by Bluetooth and your mind

Robotic limbs aren't a new technology, though the range of motion and strength of such limbs continue to improve. Controlling prosthetics with your mind is another area of refinement, but they're typically connected directly to a patient's brain. A new technique where the robotic arm clicks directly to the bone, however, is showing promise. Johan Baggerman is the first patient in the Netherlands to get a click-on prosthetic arm that he can control with his mind. With a direct connection to the bone, click-on appliances like this don't need a prosthesis socket, making it easy to take on and off and avoiding chafing and other skin problems. The "mind control" is enabled by connecting a patient's nerves to the socket, with a special Bluetooth bracelet to receive the signals.
