“…One possible design for a split ring resonator is to use a CPW. A new technique was proposed by Hosseini, Olokede and Daneshmand [ 78 ] based on a Miniaturized coplanar waveguide SRR (MSRR) operating at a 1.57 GHz frequency. This technique was developed by the integration of a half-wavelength conductor and the extended capacitive coupling gap.…”

Recent developments in the field of microwave planar sensors have led to a renewed interest in industrial, chemical, biological and medical applications that are capable of performing real-time and non-invasive measurement of material properties. Among the plausible advantages of microwave planar sensors is that they have a compact size, a low cost and the ease of fabrication and integration compared to prevailing sensors. However, some of their main drawbacks can be considered that restrict their usage and limit the range of applications such as their sensitivity and selectivity. The development of high-sensitivity microwave planar sensors is required for highly accurate complex permittivity measurements to monitor the small variations among different material samples. Therefore, the purpose of this paper is to review recent research on the development of microwave planar sensors and further challenges of their sensitivity and selectivity. Furthermore, the techniques of the complex permittivity extraction (real and imaginary parts) are discussed based on the different approaches of mathematical models. The outcomes of this review may facilitate improvements of and an alternative solution for the enhancement of microwave planar sensors’ normalized sensitivity for material characterization, especially in biochemical and beverage industry applications.

“…Some of these include the production of integrated circuits, microelectromechanical systems, miniaturized sensors, biochips, micro-optical components, and diffractive optical elements [10][11][12][13]. The design and patterning of structures close to the molecular level opens up the possibility for techniques with higher sensitivity applicable for the immobilization of biomolecules [14][15][16][17]. There is a growing demand for improvements in the complexity of the generated patterns; thus, significant efforts are being devoted toward the development of newer and innovative patterning techniques; each with their own set of benefits and shortcomings.…”

The selective positioning and arrangement of distinct types of multiscale particles can be used in numerous applications in microfluidics, including integrated circuits, sensors and biochips. Electrokinetic (EK) techniques offer an extensive range of options for label‐free manipulation and patterning of colloidal particles by exploiting the intrinsic electrical properties of the target of interest. EK‐based techniques have been widely implemented in many recent studies, and various methodologies and microfluidic device designs have been developed to achieve patterning two‐ and three‐dimensional (3D) patterned structures. This review provides an overview of the progress in electropatterning research during the last 5 years in the microfluidics arena. This article discusses the advances in the electropatterning of colloids, droplets, synthetic particles, cells, and gels. Each subsection analyzes the manipulation of the particles of interest via EK techniques such as electrophoresis and dielectrophoresis. The conclusions summarize recent advances and provide an outlook on the future of electropatterning in various fields of application, especially those with 3D arrangements as their end goal.

As the surge for renewable and clean energy resources increases, new challenges emerge. One of the challenges related to the use of hydrogen as a clean energy source is safety. In this study, a microwave hydrogen sensor has been presented for detection of hydrogen leakage. An analytical model is developed and the performance of the sensor is investigated using numerical analysis tools. It has been shown that with optimal geometrical parameters of the sensor structure, a wide range of sensitivity levels depending on a wide range of Q-factor can be achieved. Utilizing a palladium disk with a radius of 750 𝝁m can detect hydrogen with a sensitivity as high as 30 MHz per % hydrogen when g = 10 𝝁m. Average error between analytical model and numerical results is 0.23%. With reference to this work, it is believed that more compact and sensitive microwave hydrogen sensors will be produced for future uses.
