摘要: 监测人体体征参数有助于尽早发现潜在疾病、指导临床干预及促进康复。与电容传感、电感传感、微型涡轮传感、热敏电阻传感等传统传感器相比,光纤布拉格光栅(fiber Bragg grating, FBG)传感器线性度好、灵敏度高、抗电磁干扰且易于集成,在人体体征监测中具有良好前景。系统梳理了FBG传感器在体温、血压、脉搏、呼吸四大体征参数监测中的应用现状,得出FBG传感器在四大参数监测中均具有可行性,其在信号质量与舒适度方面有所提升,多参数联合监测成为研究热点,未来需结合智能算法与集成化设计推动临床早期预警与远程康复应用。Abstract: Monitoring of human vital signs facilitates early detection of potential diseases, guidance for clinical intervention, and promotion of rehabilitation. Compared with traditional sensors such as capacitive, inductive, micro-turbine, and thermistor sensors, fiber Bragg grating (FBG) sensors are characterized by good linearity, high sensitivity, anti-electromagnetic interference, and ease of integration, and thus are considered to have promising prospects in human vital sign monitoring. The application status of FBG sensors in monitoring four major vital sign parameters (body temperature, blood pressure, pulse, and respiration) was systematically reviewed. It is found that FBG sensors are feasible for all four parameters. Improvements have been achieved particularly in signal quality and comfort. Multi-parameter combined monitoring is recognized as a research hotspot. Future efforts should focus on integrating intelligent algorithms and compact design to promote clinical early warning and remote rehabilitation applications.
