This study based on carbonized silk fiber with different twist orientations presents a kind of high sensitivity, large strain range and high selectivity of two-dimensional flexible resistive strain sensor. The sensor can effectively identify the direction and size of the strain in the plane. The sensitivity (GF) of the sen-sor can reach 18.70, the strain detection range can reach 100%, the sensitivity ratio of X axis to Y axis is more than 100 times, and has more than 500 times of cyclic tensile stability, which can real-ize the sensing detection of strain size and direction.
