半导体光电传感器,由于其具有体积小,响应快、灵敏度高易集成化和智能化等特点,受到人们重视．特别在生物医学工程领域已基本满足无创实时监测人体中各种重要的生理指标,诸如血氧饱和度,呼气末二氧化碳,血糖浓度,脑血氧饱和度等的要求,在临床中已见使 Semiconductor photoelectric sensor, due to its small size, fast response, high sensitivity and easy integration and intelligent features, by people attention. Especially in the field of biomedical engineering has basically meet the non-invasive real-time monitoring of the body’s various important physiological indicators, such as oxygen saturation, end-tidal carbon dioxide, blood glucose levels, cerebral oxygen saturation requirements have been seen in the clinical
