“…Non‐invasive methods are in high demand to take the place of the traditional finger‐prick method as they can facilitate continuous glucose monitoring 4 . A variety of minimally or non‐invasive blood glucose monitor (NIBGM) devices based on various interesting technologies have been introduced over the last few decades, 2,10–13 pursuing their way towards obtaining the necessary approval to enter the market 2 . Some other methods have been investigated, 14–17 although conclusive results have not been found yet 18 .…”

“…With the advancement of wireless technologies in the last decade, there has been a rising interest in interacting electromagnetic waves with biological tissues. During this period, researchers looked into the possibility of using radio‐frequency (RF) or microwave sensors to characterize blood glucose levels 9,13,14,19–21 . Therefore, when it comes to non‐invasive measurement, sensors based on electromagnetic fields or antennas are commonly used.…”

The current study focuses on a non‐invasive microwave system based on a UWB antenna for blood glucose measurements in the frequency range of 1–4 GHz. Calculations of the minimal values of microwave reflection coefficient (S11 Min) corresponding to various blood glycemia, as well as comparisons to measured values using the Vector Network Analyzer Anritsu MS46121B, were the major findings of this study. The results were in good agreement, with a shift of less than 5%, demonstrating the effectiveness of our microwave method in detecting blood glycemia. To define an experimental approach between blood and dextrose solution, a comparative study in terms of slops in a linear approximation of both S11 Min and resonant frequency versus glucose concentration for the two mediums was interesting. The deviations in the results are less than 5% in the range of 1–2 GHz. However, it is not the case in the ranges of 2–3 GHz and 3–4 GHz since the two mediums show contrary behavior regarding S11 Min and resonant frequency. Consequently, D‐Solution might be used to simulate blood using our system for the investigation of glycemia only in the range of 1–2 GHz.

“…In a series of publications [4,[10][11][12] by the authors from Cardiff University, the design of a microwave non-invasive sensor for continuous monitoring of the blood glucose level was described in detail. The novelty of the design was that the sensor contained two splitring resonators with a gap.…”

Application of Broadband Microwave Near-Field Sensors for Glucose Monitoring in Biological Media

The paper presents results of numerical simulation and experimental testing of a microwave sensor for non-invasive glucose monitoring. The sensor represents a conical horn with a conical conductor inside expanding toward the horn aperture. Such a sensor has a significantly wider passband in comparison with sensors of other designs. It is essential that the sensor geometry provides formation of an extended near-field zone with high electric field strength near the sensor aperture. A clear relationship between the dielectric permittivity of the phantom biological tissue and the frequency dependence of the parameter S11 of the sensor is observed at frequencies in the range from 1.4 to 1.7 GHz. This circumstance can be used to develop a procedure for measuring the glucose level in blood that correlates with the parameter S11 of the sensor. From the viewpoint of monitoring of the glucose content in blood, the most convenient body sensor location is on the hands or feet, in particular, wrists.

“…However the maintenance costs for lancets, needles, and test-strips are not negligible, not to mention the pain and the risk of infection. Continuous glucose monitors (CGMs) based on tiny flexible subcutaneous needles have recently been gaining popularity [2]. One of the merits is that they provide history and continuous trends of glucose levels.…”

Previously reported clinical performances of microwave noninvasive blood glucose monitoring sensor look promising. It is clear that dielectric properties are changing when the food intake takes place, but the exact physiological mechanism is not clear. In an attempt to figure out the physiological mechanism of microwave noninvasive blood glucose monitoring sensor, this paper presents a series of studies to find out a) the penetration depth of the microwave resonator-based sensor and b) the effect of permittivity variation of human tissues on the microwave resonator parameters.
