1. A high-power bidirectional-driven bionic muscle fiber, comprising a matrix fiber and an object material layer coating the matrix fiber, wherein,
the matrix fiber is configured for emitting a heat after an electrification, and the object material layer coating the matrix fiber comprises a liquid crystal elastomer (LCE);
the high-power bidirectional-driven bionic muscle fiber is twisted to have a helical barrel-like structure.
