Figure 5: Current response of monolayer MoS2 strain sensor.

Current response of CVD monolayer MoS2 device at repeated compressive (a) and tensile (b) strains at a fixed bias voltage of 1 V. (c) Measured current response when the device is free of strain (0 nN) and under mechanical loads equivalent to 5 and 10 nN, respectively. (d) Rise time and decay time of the MoS2 piezotronic device.
