Abstract: (1283 Views)
In this paper, we present a skin-pressure sensor with graphene based on Surface Plasmon Resonators (SPR) mechanism. The result of applying body pressure is a change in the period grating. The SPR excite in a specific wavelength with placing graphene on the SiO2 substrate. The simulations have been done in two parts, mechanical (by FEM method) and plasmonic (by FDTD method). Pressure changes in the mechanical part are in the range of 0 to 300mmHg and the wavelength is determined according to each pressure. In other words, a unique wavelength has been determined for each pressure by connecting the results of each section. Fast responses, repeatability, ability to develop parameters measurement and wide range of pressure are among the advantages of this sensor.
