A bionic neuromuscular fiber as well as a preparation method and use thereof are provided. The bionic neuromuscular fiber includes a carbon nanotube fiber core, an intermediate layer, a substrate layer, and a sensing layer which are coaxially and successively sheathed from inside to outside, and is twisted to form a helical shape. The intermediate layer and the substrate layer are both made of polymer materials, and the thermal expansion coefficient of the intermediate layer is larger than that of the substrate layer. The sensing layer includes a carbon-based conductive material at least containing MXene. In the present application, the sensing layer and the intermediate layer are both multifunctional, the sensing layer is used as not only a capacitor electrode but also a resistance sensing element, and the intermediate layer is used as not only a thermal driving element but also a dielectric layer.

Bionic neuromuscular fiber as well as preparation method and use thereof

A high-power bidirectional-driven bionic muscle fiber as well as a preparation method and use thereof are provided. The bionic muscle fiber includes a matrix fiber and an object material layer coating the matrix fiber, where the matrix material is capable of emitting heat after electrification, and the object material layer includes a liquid crystal elastomer (LCE); the bionic muscle fiber is excessively twisted to form a helical barrel-like structure. The bionic muscle fiber provided by the present application improves the mechanical property of the LCE, shows large work capability and drive quantity, and has an realize rapid response and work at high frequency. The contraction of the fiber can be controlled by changing voltage. Furthermore, the bionic muscle fiber exhibits a bidirectional driving feature that can recover without stress. In addition, the cyclic work of the fiber is greater than zero.
