A new prosthetic hand can be controlled by an iPhone.

A prosthetic arm has been invented that can be controlled by an Apple iPhone app, coupled with muscle reflex movements.

A robotics firm in Livingston called Touch Bionics has created the i-limb, which gives the user 24 different grip patterns.

Costs for the i-limb prosthetic vary from 60 thousand to 120 thousand dollars.

Karen Hakenson from Touch Bionics said: "To fit an i-limb prosthesis, clinical practitioners undergo extensive training to build the skills needed to help patients gain the maximum possible functional benefit from their device."

The mobile app that works together with the i-limb is call bioism.

Another one of the latest developments in prosthetic technology is a limb that can be controlled by a person’s thoughts.

By attaching electrodes that give feedback from nerves and muscles in the limb, the scientists from Chalmers University of Technology in Sweden have made arms that are controlled simply by the patient’s thoughts.

Each finger has a separate motor for a range that is closer to matching natural movement.
