Hierarchical Artificial Muscle with Nonlinear Elasticity for Antagonistic and Cyclic Robotics
We construct hierarchical muscles by plying nylon fibers around a heating wire. The hierarchical muscle shows a J‐shaped passive curve, which shows benefit in antagonistic muscle pair and work accumulation mechanism. We also develop a computational, first‐principle model to understand the physics of both active actuation stroke and passive J‐curve ...

This work proposes a reliable strategy to elucidate the structure and composition of conjugated donor‐acceptor block copolymers. The method, based on NMR analysis, allows to extract key structural information such as the number of heterojunctions (NoH) and the number of blocks (NoB) of the copolymers.
