Available in PDF, EPUB and Kindle. Book excerpt: Non-invasive measuring techniques for determining biological parameters are more heavily researched with the growth of the biomedical industry. One of the top areas in non-invasive research deals with diabetes. This disease affects more than 20 million people in the United States, and there is an increasing desire to find a testing process that is non-invasive, easy to use, and safe for users. Microwave technology has improved greatly during recent years and is now seen more often in conjunction with biomedical research. Microwaves are capable of taking measurements of materials inside of a closed volume without the need to come into contact with the material. This makes them ideal for measuring biological parameters, specifically glucose concentrations in the blood. This thesis expands on the development of a microwave sensor to non-invasively measure blood glucose levels and will examine the possibility of developing a calibration for a device using the microwave sensor.
Book Synopsis Calibration for Real-time Non-invasive Blood Glucose Monitoring by : Matthew Sidley

Available in PDF, EPUB and Kindle. Book excerpt: "Blood glucose monitoring is a primary tool for the care of diabetic patients. At present there is no non-invasive monitoring technique of blood glucose concentration that is widely accepted in the medical industry. Some promising success has been shown by the RIT ETA Lab research group that an antenna's resonant frequency can track, in real time, changes in glucose concentration. However, these changes in antenna response would be unique to an individual depending on various parameters such as the person's metabolism, body mass index, chemical profile etc. Therefore, amongst the several issues that still need to be addressed in the development of a noninvasive methodology; an important one is the calibration unique to each individual patient. The objective of the present work is to establish a calibration by developing an equivalent circuit model to represent the antenna input impedance with changing glucose levels. Using the calibration, the glucose level is estimated from the measurement of antenna impedance and resonant frequency at a later date. Measurements were made on a diabetic and non-diabetic subject with a blood glucose meter and with a planar dipole antenna connected to a network analyzer. The network analyzer was automated to make input impedance measurements in real-time using Labview in 15 second intervals and calculates the resonant frequency of the antenna. The resonant frequency of the antenna and the reference glucose values using a blood glucose meter were measured. The resonant frequency of the antenna is plotted in real-time for instant analysis and trends. A linear estimation for the glucose based on the resonant frequency of the antenna was compared to reference measurements taken by a blood glucose meter. 59% estimates were with 20% of the reference measurements for the diabetic patient. An equivalent circuit model, developed to estimate glucose concentration, was found to have a shunt resistance, series capacitance, and shunt inductance. The component values for this circuit are generated from the experimental results of the diabetic patient, unique to the subject. The component values are iteratively varied until they reflect the impedance of the input impedance. Because the input impedance is changing over time, the component values change over time. The calibration model uses fitted equations to the component values from the experimental result that relates the component values to a glucose concentration. This unique equation for the diabetic patient can be used to estimate the glucose level when measuring the input impedance of the antenna at a later date. The experiment was repeated on the diabetic subject and the unique calibration procedure was used to estimate the blood glucose concentration. The estimates represented by the Clarke's Error Grid compared favorably to the measurements made by the blood glucose meter."--Abstract.

Download or read book Multivariate Calibration Techniques for Noninvasive Glucose Monitoring written by Syed Rameez Naqvi and published by LAP Lambert Academic Publishing. This book was released on 2014-05 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diabetes is a rapidly growing disease that can cause several types of disabilities, and even death. No cure to this disease has been discovered as yet; the only solution is to monitor, and keep the level of glucose in blood controlled. Unlike the finger-prick method, non-invasive monitoring, through IR spectroscopy, is a convenient and harmless way of measuring the glucose level. In principle, a beam of light is focused on a part of body to excite the molecules, which either absorb this light partially or transmit some radiations in response. These radiations may be collected and unique response that different components of a blood serum show to this light may be observed in a form of spectra. Since glucose is not the only component present in blood, the multivariate calibration techniques are used to isolate the glucose spectrum from the collected spectra. This work presents a comparison between various multivariate calibration techniques in terms of their precision under varying signal-to-noise ratios. The presented results are useful, especially for the researchers working to develop a non-invasive glucose monitoring device, in making a choice between the available techniques.
Book Synopsis Designing Microwave Sensors for Glucose Concentration Detection in Aqueous and Biological Solutions by : Carlos G. Juan
Download or read book Designing Microwave Sensors for Glucose Concentration Detection in Aqueous and Biological Solutions written by Carlos G. Juan and published by Springer Nature. This book was released on 2021-06-14 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive study covering the design and application of microwave sensors for glucose concentration detection, with a special focus on glucose concentration tracking in watery and biological solutions. This book is based on the idea that changes in the glucose concentration provoke variations in the dielectric permittivity of the medium. Sensors whose electrical response is sensitive to the dielectric permittivity of the surrounding media should be able to perform as glucose concentration trackers. At first, this book offers an in-depth study of the dielectric permittivity of water–glucose solutions at concentrations relevant for diabetes purposes; in turn, it presents guidelines for designing suitable microwave resonators, which are then tested in both water–glucose solutions and multi-component human blood plasma solutions for their detection ability and sensitivities. Finally, a portable version is developed and tested on a large number of individuals in a real clinical scenario. All in all, the book reports on a comprehensive study on glucose monitoring devices based on microwave sensors. It covers in depth the theoretical background, provides extensive design guidelines to maximize sensitivity, and validates a portable device for applications in clinical settings.
Book Synopsis Design of a Microwave Sensor for Non-invasive Determination of Blood-glucose Concentration by : Eric C. Green
Download or read book Design of a Microwave Sensor for Non-invasive Determination of Blood-glucose Concentration written by Eric C. Green and published by . This book was released on 2005 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diabetes is a disease that afflicts millions worldwide. To control the effects of this disease, diabetics must check their blood glucose levels on a regular basis. Currently, all daily glucose monitoring techniques are invasive, requiring a sample of blood. Microwave sensors are non-destructive and non-contact measuring devices, making them ideal for the measurement of parameters in industrial processes. Current uses of microwave sensors range from measuring moisture content of corn chips to measuring concentration of a solute in water. If a microwave sensor were developed to determine blood glucose concentration, it could be the first daily-use glucose-measuring technique that is truly non-invasive. This thesis provides background on diabetes and microwave measurement. From this background, a sensor is developed and its advantages are illustrated. The thesis concludes by making suggestions for improving the sensor and recommendations on how to implement the sensor into a useful product.

Book Synopsis New Methods for Determining the Complex Permittivity of Different Glucose Concentrations by Waveguide and Antenna Measurements at V-band by : Helena Cano García
Download or read book New Methods for Determining the Complex Permittivity of Different Glucose Concentrations by Waveguide and Antenna Measurements at V-band written by Helena Cano García and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [ANGLÈS] Diabetes is a metabolic disease that affects millions of people in the world. To control the status of this disease, diabetic patients have to measure continuously their glucose levels during all day. Nowadays, the method to monitor the glucose content in blood is called finger prick test. This method is very accurate, but it is also painful and invasive and, over the long term, it can damage the finger tissue. For this reason, this thesis presents two new and non-invasive methods to determine the glucose content in blood without any harmful effect. These new methods present two different forms to detect the glucose content using microwaves in the frequency range between 50 GHz and 75 GHz. The first method is based in a waveguide structure consisting of two waveguides and a tank containing the sample between them. The second method uses a similar structure to the first method, but instead of using waveguides, it uses antennas. To study both methods the CST simulation software package has been used. CST's versatility allowed us to perform various realistic electromagnetic (EM) simulations and extract the desired S-parameters for each scenario. The analysis of the first method has shown that the simulation results and the experimental results are really similar. This first analysis has also shown that plane wave propagation is necessary in order to apply the post processing analysis employed in this work. To satisfy the plane wave requirement, a second setup based on antennas in the far field has been used. In this case, the results of the post processing part were not as good as expected. This might result from the association of the TRL calibration and NRW algorithm for fulfil the plane wave requirement. For this reason, further analysis involving the development of our own calibration procedure will be required.
