Researchers have created artificial muscles that can twist 1,000 times more than any material made in the past. This development could prove useful in the development of robots and prosthetic limbs. Artificial muscles are typically made from polymers and metals that change size and shape. However, to be truly useful, these materials need to twist or rotate when an electric current is applied, and very few materials can do this. The new muscles can produce as much torque, or twisting force, as commercial electric motors.
