  8. The World Health Organization (WHO) in 2016 came up with the first global report on diabetes that provided significant leads towards understanding diabetes. The report calls for stronger responses from the society to best utilize science for developing affordable medical technologies for effectively addressing diabetes. In recent years, it has been reported by many research groups that the microwave technology can be effectively utilized to devise an alternate cost-effective methodology for estimation of glucose in blood leading to regular screening and early diagnosis of diabetes.
    Since blood glucose measurement requires sample blood specimens, the amount of blood to be tested/drawn becomes a critical factor when RF testing of such measurements is carried out. The device reusability is another factor that must be deliberated while designing RF sensor systems for glucose detection in blood. When the test sample comes in direct contact with the sensing region, even after flushing out, the sample leaves an imprint on the sensor that may alter further measurements using the device. This factor should also be properly addressed during the design scheme.
    The developed resonant sensor using the planar technology for blood glucose estimation would primarily be judged on following major criteria:
    1. Relative sensitivity (∆𝑓/[𝑓0∆𝜀𝑟] × 100%): ≥ 7-8%
    2. Sensitivity of glucose detection (MHz/mgdl-1):
    3. Quality factor: ≥ 10
    4. Size (electrical dimensions): compact size!!
    5. Minimum level of glucose estimation (mg/dl):
    6. Structure novelty;
    7. Minimum amount of blood required for testing (ml/µl):
    8. Reusability of the sensor prototype.
