“…These properties are highly demanded in the food industry for quality control. In turn, the use of nanomaterials or combinations between materials (that favor synergies in their electrocatalytic activity), applied via new preparation methodologies, will allow for the obtaining of more effective arrays [8,9]. Methanogenic markers appear in concentrations of very low orders of magnitude, which is why the introduction of nanomaterials is so necessary; it allows for the detection of trace-level components.…”

“…They are present and exist in many different applications and continue to play a crucial role. Some of the most common applications are the detection of explosive gases and toxic vapors [3], food quality control [4], oxygen monitoring in the medical sector [5] and environmental monitoring of the air quality [6]. Today's need for small, low-power, and easy-to-use sensors has enabled the continued development of this technology.…”

The author of this article illustrates a new design and simulation of a twodimensional photonic crystal (PhC) based hydrostatic pressure sensor with a wide dynamic range that ranges from 0 to 4 Gpa and is conducted at a high resolution using the Finite Elements Method (F.E.M) under COMSOL software. In order to analyze the detection principle and its characteristics, the sensor is based on a triangular array PhC-2D of air-immersed silicon rods with a refractive index of 3.6 is used. The sensor consists of a hexagonal shaped ring resonator, which sits between two obtuse angle shaped waveguides. The two waveguides are configured by removing a row of B rods (line faults) and the ring resonator by removing a few rods. This ring resonator reduces the effect of external parameters such as humidity, temperature, etc. The band diagram is presented as well as analyzed using the plane wave expansion (PWE) under the Mat lab software on the one hand and on the other hand, on the other hand, results are obtained and illustrated such as: the distribution of the refractive index 'n' within the structure with the mesh, the distribution of the electric field (TE) at resonance in 2 and 3D, the total energy density (TED), the power flow norm (PFN) and transmission. The sensor is designed for wavelengths between 1520nm and 1640nm.The simulation results show that due to the applied pressure, the refractive index of a sensor is changed and thus the resonant wavelength is shifted linearly to longer wavelengths.The designed sensor behaves linearly between 0GPa and 4GPa of applied pressure and 4.6 nm/GPa of pressure sensitivity.
