A bionic neuromuscular fiber, comprising 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, the bionic neuromuscular fiber being twisted to form a helical shape;
- the intermediate layer and the substrate layer being both made of polymer materials, and the thermal expansion coefficient of the intermediate layer being larger than that of the substrate layer;
- the sensing layer comprising a carbon-based conductive material at least containing MXene.
