A Minimally Invasive Implantable Sensor For Continuous Wireless Glucose Monitoring Based On A Passive Resonator

An implantable biosensor for the long-range continuous glucose monitoring is proposed in this letter. A fully passive, miniaturized circuit composed of an LC (inductor-capacitor) tank resonator with a volume of 16 mm3 is developed. This passive circuit can be implanted under the human skin, where the interstitial dermal fluid surrounds the LC tank resonator. Variations in glucose concentration res...
