The invention discloses a Ti3C2Tx flexible strain sensor and a preparation method thereof, and belongs to the technical field of flexible sensors. The flexible strain sensor comprises a flexible substrate, a U-shaped sensitive layer arranged on the flexible substrate and an electrode layer connected to the sensitive layer. The sensitive layer and the conductive layer are arranged on the substrate and are prepared by adopting a refill drawing method, the sensitive layer is constructed by m-Ti < 3 > C < 2 > T < x > ink with at least three groups of different microstructures, and the conductive layer is constructed by single-layer s-Ti < 3 > C < 2 > T < x > ink. Ti3C2Tx is selected as an electrode and a sensitive material, and the material is simple in preparation process and low in cost and has the advantages of hydrophilicity and conductivity at the same time; two kinds of ink containing different microstructures are deposited on the paper substrate in a direct writing mode to serve as the conducting layer and
