Engineers at the Cleveland Clinic in Ohio have developed a bionic arm which allows a person who wears it to touch, move and feel things like with a natural arm.

The scientists say they've tried to design the arm so it can be cheaply produced.

Dr. Paul Marasco, Director of the laboratory for bionic integration at at the Cleveland Clinic and lead investigator on the project, says users start to forget they're wearing a prosthesis.

"Your brain takes over and it starts behaving in an innate and reflexive way... It releases the person with an amputation from having to attend to all the minutiae that your body does naturally."
