Minimally-invasive blood glucose monitoring is a very efficient and important way to control blood glucose level of diabetes. An implantable fiber-optic surface plasmon resonance sensor for minimally-invasive blood glucose monitoring is presented. As the fiber-optic SPR sensor is sensitive to temperature and moreover the human body temperature drift plays a great effect on measurement results when the sensor is implanted in human body, long period fiber grating (LPFG) is utilized for temperature compensation to improve measurement accuracy. The fiber-optic surface plasmon resonance sensor is theoretically analyzed and the parameters such as the length of sensor, diameter of fiber, thickness of Chrome and gold are calculated and simulated. The parameters of LPFG is analyzed and simulated, such as length, period and modulation depth. The structural parameters of the sensor are optimized through the calculation and simulation.
