Abstract
Blood glucose monitor system is designed with the core of photonic crystal fiber(PCF) and technology of small-invasive photoelectric.According to the principle that different blood glucose concentration absorbs different light
optical modulation is controlled by MSP430.Light is emited to the blood samples through transmission of three probe fiber-optic sensor.The reflected light is inputed to MSP430 after photoelectric conversion.Blood glucose concentration is calculated after A/D conversion.The system has characteristics of easy-operation
