- Abstract
In this paper, we present a numerical design of a pressure sensor using surface plasmon resonance (SPR) based on Fabry–Perot interferometer mechanism with focus on MoS2 and graphene monolayer nanomaterials. These two-dimensional nanomaterials increase the sensitivity of the device. The proposed sensor consists of two parts: mechanical structure and SPR detection part, both of which have been examined. Sensing range of the proposed sensor is 0–160 MPa with a sensitivity of 300 nm/GPa. By making a theoretical link between mechanical structure and optical detection parts, we have completely simulated the sensor and evaluated the results. The pressure sensitivity of the MoS2 monolayers can provide an opportunity for nanoscale pressure sensors as well as applications in electronic, flexible, and nano-electronic devices. We used of FDTD method for the optical section and FEM method for the mechanical structure to evaluate the performance of the proposed sensor.
