Artificial Muscle Fibers for More Realistic Humanoid Robots

Artificial muscles - materials that contract and expand somewhat like muscle fibers do - can have many applications, from robotics to components in the automobile and aviation industries. Now, MIT researchers have come up with one of the simplest and lowest-cost systems yet for developing such 'muscles,' in which a material reproduces some of the bending motions that natural muscle tissues perform. The key ingredient is ordinary nylon fiber.
