Proje Özeti

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. One of the recent approaches has been the use Radio-Frequency (RF) sensors for non-invasive BGL monitoring. In this project, compact size and highly sensitive RF sensor will be designed, developed, fabricated and tested. Two technological challenges will be addressed in the RF sensor design; compactness or small size and high sensitivity. Then, based on the publications in the literature, three major approaches will be investigated; i) use of substrate integrated waveguide (SIW) technology as the host of the sensor, ii) use of complementary split ring resonator (CSRR) and/or inter-digital capacitor (IDC) topologies as sensing section of the sensor iii) differential mode operation of whole sensor. The finalized sensor is expected to meet the targeted requirements of size and sensitivity. The Printed Circuit Board (PCB) based fabrication is expected to help reduce the cost, and leads to mass production.

This 18-months duration project has a team of four researchers from two universities, Islamic Azad University of Urmia from Iran and Gazi University from Turkey. One consultant from University of Bath will be contributing to the project with his experience on prototyping and fabrication of such sensors. The research team have electrical engineering and biomedical engineering backgrounds, and some have already published, in top-tier journals on similar sensor designs, and filed a patent. Several graduate students are expected to be conducting thesis studies within the project or closely related areas. The team will be working in three work packages, one of which is dedicated to valorization activities where industry sponsored follow up projects, aiming transition of the project outcomes (TRL5) to commercialized device (TRL9), are planned to be developed.
