Item Calibration methodology for a microwave non-invasive glucose sensor.(2008-06-09T15:41:02Z) McClung, Melanie J.; Jean, B. Randall.; Engineering.; Baylor University. Dept. of Electrical and Computer Engineering.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.Item A microwave radiometer system for use in biomedical applications.(2007-02-21T22:39:34Z) Ballew, Laura R.; Jean, B. Randall.; Engineering.; Baylor University. Dept. of Electrical and Computer Engineering.The biomedical industry is a rapidly growing sector and demands are increasing for the production of safe and noninvasive technologies. With the current surge of diabetes, a very desirable application for these technologies is a non-invasive monitor for blood glucose level. Recently, microwave sensing has offered hope for safer diagnostic and therapeutic procedures. One specific sensing technique involves a microwave radiometer, which provides a purely passive measurement of naturally emitted electromagnetic radiation from material objects. A highly sensitive receiver, the radiometer can detect radiation for the purpose of obtaining useful information about a particular object, thus providing a safe tool for the biomedical industry. This thesis outlines the microwave properties of radiometry and presents the design of a microwave radiometer aimed at biomedical applications. Experimental results demonstrate the applicability and repeatability of the device, as well as its performance as a biomedical sensor.
