Magnetic-Field-Driven Artificial Muscle based on the H. Huxley Model: Fundamental Experiments

We experimentally demonstrate an artificial muscle driven by an externally applied magnetic field. The drive mechanism simulated a model proposed by H. Huxley for bionic muscle contraction. Small magnetic needles swing with a time-varying magnetic field and enable linear motion of an object on the needles. In the future, this fundamental mechanism could prove useful for realizing linear actuators for robots.
