Fabrication of the flexible MoS₂ film strain sensor and electromechanical behavior

(A) Flow diagram of the fabrication of the flexible MoS₂ film strain sensor.

(B) The flexible MoS₂ film strain sensor response under forward bending. The inset graph is the enlarged area of the sensor response from 0 to 30 s. The inset photographs were taken during the forward bending state under different ΔL.

(C) The strain-dependent sensor response and GF.

(D) Relative MoS₂ film strain sensor response during 1,000 stretch and release cycles.
