Researchers from MIT and Politecnico di Bari have developed electrically driven artificial muscle fibers that contract and extend like biological muscle without motors, gears, or external pumps. Each fiber contains a sealed fluid circuit and a millimeter-scale electric pump that shifts liquid between two actuators, causing one to contract while the other relaxes. The fibers are silent, scalable by bundling like natural muscle, and thin enough to distribute throughout a robotic structure rather t
