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.
