Checking blood sugar levels regularly is very important in good diabetes management. Most methods of blood sugar monitoring need a blood sample.

Blood sugar monitoring can be done at home with a variety of devices. They take the blood sample by pricking your skin with a small tool. A small device called a glucose meter or glucometer measures how much sugar is in the blood sample.

The drop of blood you get with a finger prick is often enough to use on a test strip. A finger prick can be done with a special needle lancet or with a spring-loaded device that quickly pricks the fingertip.

You place the drop of blood on the test strip. Depending on the type of meter used, you may put the strip into the meter before or after you put the drop of blood on the test strip.

The meter then reads the blood sugar level. Most meters are made to be used with the finger prick blood drop. But some meters can also be used with blood taken from the forearm or other site.

You can choose from many types of monitors. They range in price, ease of use, size, portability, and length of testing time. Each monitor needs a specific test strip. Generic strips or strips for other monitors may give inaccurate readings.

Always refer to your user's manual for directions. Most blood sugar monitors give accurate results if used correctly. Most give results within seconds.

Some monitors can also talk. They give directions and results that you can hear. This is helpful if you have vision problems.

Or if you have physical problems that make it hard for you to see the results. Some monitors can give spoken directions in Spanish and other languages. Some monitoring devices can monitor blood sugar continuously for several days at a time.

You may be able to set an alarm on the device. This can warn you if you blood sugar gets too low or too high. You may have to check your blood sugar levels 4 or more times a day.

Blood sugar levels can be affected by several things. These include:. Limited sensitivity of the traditional resonator is as the result of confined electromagnetic fields between the resonator and its ground plane see Fig.

In traditional resonators, because of this phenomenon, substrate has a more important role in defining the resonance frequency rather than MUT. Because of the removing of the substrate for the tag in the presented work, the main variable parameter defining the resonance frequency of the tag is the MUT permittivity.

For studying this concept, another simulation has been accomplished for both conventional and presented resonators. As depicted in Fig. It could be seen that, for traditional resonator sensors, substrate permittivity is the dominant parameter in determining the resonant frequency of the structure while the impact of substrate permittivity variations on the proposed sensor is very small and even negligible.

Sensitivity comparison between the presented sensor and traditional microwave resonator sensors. a Proposed sensor sensitivity test setup with a superficial material with the relative permittivity between 1 bare resonator and b Traditional microwave resonator sensor with the same volume and permittivity.

It could be seen that, frequency shift related to the proposed sensor is MHz c in comparison with MHz for the traditional sensor d under the same condition.

Comparison between the impact of substrate in determining the resonance frequency of the traditional and proposed sensors. Frequency shift versus MUT permittivity for different permittivity values for substrate for a traditional sensors, b proposed sensors; it could be seen that the effect of substrate permittivity in traditional resonator sensors is dominant while its impact is negligible for the proposed sensor.

This is the reason of higher achieved sensitivity of this design in comparison with the traditional sensors. Another notable feature of the presented work is the distant sensing capability. This characteristic is especially important for wearable electronic applications.

In addition to capability of embedding the reader in a smart watch, phone or a gadget, this remarkable feature brings up new paramount benefits such as zero power consumption, extremely low cost, and small size for the sensing tag. For having a better insight into this characteristic, another simulation has been accomplished by placing MUT with specific relative permittivity on top of the tag and increasing the distance between the reader and the tag.

It could be seen in Fig. a Simulation setup for characterization of distance measurement of the proposed sensor image is obtained from HFSS. b Definition of the notch to signal floor ratio NSFR for the presented simulation.

c NSFR of the signal versus the distance of the sensor from the reader. Various measurements have been accomplished verifying the performance of the proposed non-invasive glucose measurement sensor.

First of all, glucose concentration measurement in deionized DI water is carried out. Figure 6 d sketches the resonance frequency notch amplitude of S21 response of the sensor. It could be seen that the sensor response is both stable and repeatable. Also, high sensitivity characteristic of the sensor is noticeable.

This means, the response of the sensor is less susceptible to environmental noises than its conventional counterparts. It could be seen that the response of the sensor is very consistent and repeatable. For the next step, samples are prepared with 10 volumetric percent of horse serum for modelling ISF.

Both return-to zero and small variations of glucose concentration samples have been tested with promising results achieved as sketched in Fig. For achieving a better idea on the performance of the sensor, it is common to address the glucose concentration versus frequency shift as the measured data.

An interpolation curve fitting process then accomplished based on the resulting data. These results are presented in Fig. b Amplitude variations versus glucose concentration from the same experiment.

c Frequency shift versus glucose concentration. if we had return to zero results we could integrate them with this fig as well , d a calibration curve for glucose concentration versus the measured frequency shift.

Note that the calibration curve provides a reasonable fit with the data point despite of some errors which may be related to slight variability in the experimental samples. To further mimic a more physiological condition, we performed glucose sensing experiments through a layer of mouse skin.

In these experiments, saline is included in the sample with electrolytes and ionic concentrations described in " Results and discussion " section. According to conductivity increasing of the samples, the amplitude of the notch frequency is increased.

For this experiment, a shaved mice skin with about µm thickness wrapped inside a sealed plastic bag is used between the sensor and the liquid. Hence, the sample is located in further distance from the sensor. However, the sensitivity of the system to changes in glucose concentration is still superior to other non-invasive technologies published to date.

It could be seen that, the proposed sensor presents a stable and repeatable response over time. b Frequency shift of the sensor as the response of small variation of glucose concentration. Although microwave resonators possess impressive characteristics, there is still a very challenging issue remained.

Since any variation in the permittivity of MUT is reflected in frequency shift of the resonator, there is a concern about the uncertainty of the actual source of frequency shift. For addressing this issue, an extensive discussion part including some experiments is provided.

Beside water and plasma, ISF also contains glucose, fatty acids and salts. So far, glucose variation effects have been tested. Here, we provide some experiments for studying the effects of mineral variations on the frequency shift of the sensor.

The main ions in ISF are, sodium, potassium, chloride, calcium, magnesium, bicarbonate and phosphate. Since sodium and chloride ions have one or more orders of magnitude higher variation range in comparison with the other ions, for the sake of simplicity, they are considered as the only variable ions the experiments.

It could be seen from Fig. Hence, since frequency change is considered as the main output of the sensor, ionic concentration variations is unlikely to not interfere with results from glucose related frequency shift.

It could be seen that saline concentration has in important impact on the amplitude of the response but its resulting frequency shift is less than 20 KHz which is completely negligible.

The case would be even more negligible in real life case, because of less variations in the electrolytes. Another important parameter to consider is ionic concentration changes that manifest as a result of hydration levels.

For example, mild dehydration often occurs regularly in humans. Dehydration directly affects the water content in ISF and therefore could change its permittivity and consequently affects the performance and precision of the sensor. Sample preparation method is presented in the next section.

Figure 10 presents the frequency shift versus dehydration percentage with all the other variables remaining constant. However, severe dehydration has the potential to interfere with the frequency shift resulting from glucose variations and therefore compromise the glucose sensitivity of the sensor.

Therefore, further development of this sensor technology will have to consider the impact of severe dehydration on sensor accuracy. Frequency shift as the results of dehydration. So, one could consider the effect of low to moderate dehydration as a minimal error which is less than the impact of 0.

A comprehensive comparison between the presented structure and some of the state-of-the art works using methods other than microwave is outlined in Table 1. Another quantitative comparison between different microwave techniques-based glucose sensors and the current paper is presented in Table 2.

Although, some of the summarized works seems to have higher sensitivity than the proposed work, but those are mostly as the result of lower distances between their resonators and sample due to using of extra-thin microfluidic channels. This justification is completely in agreement with the concept presented in Fig.

sensitivity is drastically reduced with increasing the distance of the sample from the sensor in an exponential manner. We present the design and testing of non-invasive glucose sensor with a very high sensitivity despite the considerable distance between the sensor and the testing medium that would be expected in real-life biosensing applications.

The utilized sensor in this work includes two parts; sensing tag and reader, both fabricated with almost the same process. Top face of the resonator is first printed on a glossy paper using a high-resolution printer.

Printed pattern then transferred on a substrate by applying of high temperature and uniform pressure. The saline composition is designed to mimic ISF as close as possible.

A high concentration 10× stock solution is subsequently diluted with DI water to achieve actual concentration in ISF.

The pH of the resulting saline is then buffered to pH 7. The final concentrations of the prepared solution are summarized in Table 3. For dehydration testing, the saline compartments were the same and the percentage of diluting DI water was reduced according to the dehydration percentage.

Simulation in Fig. Skin samples were obtained from mice that were sacrificed for other research projects. The skin then shaved and sealed inside a plastic bag with a very small amount of saline surrounding to prevent excessive drying of the skin.

The dielectric constant of the mouse skin is about 35 59 which is in a good agreement with human skin dielectric constant used in simulations. The total exposed volume of liquid was µl. Simulations have also been carried out using High Frequency Spectrum Simulator HFSS.

Figure 11 presents the fabricated sensor including the reader and the sensing tag as well as the experimental setup. We confirm that all methods were carried out in accordance with relevant guidelines and regulations.

We also confirm that all experimental protocols were approved by Research Ethics Office REO University of Alberta. Herein, we report the design and testing of a novel non-invasive wearable glucose monitoring sensor with zero power consumption and high sensitivity that is based on microwave planar resonator technology.

The sensor is actually a metallic trace which could be taped over the skin. The impressive performance of the sensor, which removes many barriers against utilization of microwave resonator sensors for biomedical applications and especially wearable electronics, have been attained as the results of its improved design.

Moreover, substrate removal of the tag results in enhanced sensitivity of the sensor. This important improvement has been achieved as the result of making the permittivity of the MUT as the main defining parameter of the resonance frequency of the sensor. For testing the robustness of the sensor against variations of possible interferers in ISF, impacts of electrolytes variations as well as dehydration have been tested.

Any electrolyte variation effects, over a physiological range of concentrations, resulted in a negligible frequency shift of the sensor. Also, the confounding effects of low to moderate dehydration was very low but became significant for severe dehydration. In summary, our results present a novel approach to the biosensing of physiological parameters such as glucose that represents a marked improvement over existing non-invasive sensor technologies.
