In this paper, we report a new type of MoS<sub>2</sub>-based grating sensor for in-plane biaxial strain gauges with a precision limit of ~ 1‰. The MoS<sub>2</sub> grating is numerically simulated with different biaxial strains up to 5%. Our first-principles calculations reveal that the strain sensitivity of the MoS<sub>2</sub> reflectance spectrum can be considered an additional strain sensor integrated with the grating structure, enabling the mapping of in-plane biaxial strains. Our experimenta ...[more]
