Compact size and cost-effective sensors will shape the monitoring and control required for future medical diagnostics and healthcare systems. Microwave sensors with passive electromagnetic structures are very popular solutions, because of non/minimally invasive operation, low cost and high reliability. The sensing principle consists of changes in resonance frequencies in return loss, transmission zeros, or phase of insertionloss due to the dielectric loading caused by biomedical substances such as tissues and cell suspensions. Enabling diabetes individuals to self-monitor Blood Glucose Level (BGL) continuously will improve their quality of life and substantially reduce the constraints on public healthcare systems. The main excellences of the proposed sensor system are as follows
• Self and non-invasive measurement of blood glucose level (BGL)
• Highly sensitive and compact size
• Differential mode operation to remove or reduce the ambient effects.
Systematic approach for this project includes the literature survey that will concentrate on high sensitivity structures as well as small size/compact prototyping approaches. Another aspect, differential mode operation of microwave sensors will also be studied. Next, the project team will investigate different approaches to increasing the sensitivity in wide range of blood glucose level (BGL) and decreasing the size of the proposed sensor. The metamaterial design has a major role in electric field coupling in such sensor designs. Increasing the electric field density at specific small area, close to sensing region allows increasing interaction between sensor and finger. With the purpose of elimination environmental effect like temperature the differential mode operation will be developed carefully.
