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.

This book was released on 2021-06-14. Designing Microwave Sensors for Glucose Concentration Detection in Aqueous and Biological Solutions available in PDF, EPUB and Kindle. 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.

Download and read online ebook Noninvasive Blood Glucose Measurement Using Microwave Resonators write by Mahya ShahmohammadiMehrjardi. This book was released on 2020. Noninvasive Blood Glucose Measurement Using Microwave Resonators available in PDF, EPUB and Kindle. Diabetes is a serious chronic disease that has been one of the top ten leading causes of death in recent years. Constant monitoring of blood glucose is a key factor in controlling this disease. Typical self-monitoring devices require a blood drop which involves finger pricking. Due to this inconvenience, noninvasive blood glucose monitoring has been an area of great interest in the past decade. In this project, microwave resonators have been investigated in detail as proposed sensors for noninvasive blood glucose monitoring devices. Using Ansys HFSS (high-frequency structure simulator) software, several resonators have been designed, simulated, and compared. Furthermore, an experimental artificial human tissue model was created for four different blood glucose concentrations and was tested with two fabricated sensors: a microstrip ring resonator at 2.4 GHz and a complementary circular spiral resonator (CCSR) at 2.0 GHz. The measured results show the sensitivity of the resonator's S-parameters to changes in dielectric properties corresponding blood glucose levels.

Download and read online ebook Handbook of Optical Sensing of Glucose in Biological Fluids and Tissues write by Valery V. Tuchin. This book was released on 2008-12-22. Handbook of Optical Sensing of Glucose in Biological Fluids and Tissues available in PDF, EPUB and Kindle. Although noninvasive, continuous monitoring of glucose concentration in blood and tissues is one of the most challenging areas in medicine, a wide range of optical techniques has recently been designed to help develop robust noninvasive methods for glucose sensing. For the first time in book form, the Handbook of Optical Sensing of Glucose in Biological Fluids and Tissues analyzes trends in noninvasive optical glucose sensing and discusses its impact on tissue optical properties. This handbook presents methods that improve the accuracy in glucose prediction based on infrared absorption spectroscopy, recent studies on the influence of acute hyperglycemia on cerebral blood flow, and the correlation between diabetes and the thermo-optical response of human skin. It examines skin glucose monitoring by near-infrared spectroscopy (NIR), fluorescence-based glucose biosensors, and a photonic crystal contact lens sensor. The contributors also explore problems of polarimetric glucose sensing in transparent and turbid tissues as well as offer a high-resolution optical technique for noninvasive, continuous, and accurate blood glucose monitoring and glucose diffusion measurement. Written by world-renowned experts in biomedical optics and biophotonics, this book gives a complete, state-of-the-art treatise on the design and applications of noninvasive optical methods and instruments for glucose sensing.
