“…Since glucose content and the dielectric constant are directly correlated, a metamaterial sensor must satisfy the quality factor (Q) requirements for sensitivity reasons [31][32][33]. In order to increase the sensitivity, researchers usually consider different approaches to design the sensing resonators.…”

Hypersensitized Metamaterials Based on a Corona-Shaped Resonator for Efficient Detection of Glucose

et al. 2020

In this work, a new design for a real-time noninvasive metamaterial sensor, based on a corona-shaped resonator, is proposed. The sensor was designed numerically and fabricated experimentally in order to be utilized for efficient detection of glucose in aqueous solutions such as water and blood. The sensor was inspired by a corona in-plane-shaped design with the presumption that its circular structure might produce a broader interaction of the electromagnetic waves with the glucose samples. A clear shift in the resonance frequency was observed for various glucose samples, which implies that the proposed sensor has a good sensitivity and can be easily utilized to distinguish any glucose concentration, even though their dielectric coefficients are close. Results showed a superior performance in terms of resonance frequency shift (1.51 GHz) and quality factor (246) compared to those reported in the literature. The transmission variation level ∆|S21| was investigated for glucose concentration in both water and blood. The sensing mechanism was elaborated through the surface current, electric field and magnetic field distributions on the corona resonator. The proposed metamaterials sensor is considered to be a promising candidate for biosensor and medicine applications in human glycaemia monitoring.

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.

A high-precision differential microwave dielectric sensor system based on a pair of CSRR-SIW resonators is introduced. The proposed method consists of four parts: the frequency-sweeping signal source, the balanced sensor based on CSRR-SIW, the RMS power detector, and the data acquisition system. Without a vector network analyzer (VNA) and other instruments, the electromagnetic properties of materials can be measured conveniently with the proposed method. In this work, two CSRR resonators inside SIW cavities are used as the balanced RF sensing components, one for measurement and the other for ref-
