摘要
针对人体健康数据收集需要多参量且柔性安全的传感器,提出利用基于光纤布喇格光栅(FBG)的柔性传感器,对人体温度、压力和运动状态进行检测。理论分析了温度和压力对FBG反射波长漂移量的影响,以及压力对光纤光功率的影响,建立了温度传感模型、压力传感模型和人体运动模型。基于柔性基底的传感器在温度传感和压力传感方面的性能都得到了不同程度的提升。最后通过实验验证了柔性基底光栅传感器对人体温度、压力以及运动状态的监测性能。
For the collection of human health data,which requires multi-parameter and flexible safety sensor,this paper proposes to use the flexible sensor based on fiber Bragg grating(FBG)to detect the temperature,pressure and motion state of the human body.The effects of temperature and pressure on the drift of FBG reflection wavelength and the influence of pressure on the optical power of the fiber are theoretically analyzed,the temperature sensing model,pressure sensing model and human motion model are established.Sensors based on flexible substrates have improved performance in both temperature sensing and pressure sensing.Finally,the flexible base grating sensor is used to monitor the temperature,pressure and motion state of the human body.
