Abstract
Aiming at the current needs of the medical industry for measuring human body temperature and the deficiencies of several traditional temperature measurement methods, a real-time monitoring method of human body temperature using fiber Bragg grating with light weight, small size, anti-electromagnetic interference, good biocompatibility, intrinsic safety, and other characteristics is proposed. In this paper, firstly the temperature sensing characteristics of the fiber grating are theoretically analyzed. Then four fiber grating temperature sensors are calibrated by thermostatic water bath and the corresponding curve fitting is performed. Finally, the experimental results of fiber grating sensors at room temperature and fiber grating sensors under thermostatic water bath heating environment were compared and analyzed, thus verifying the advantages of fiber grating sensors. The experimental results show that in the range of 25 °C–75 °C, the center wavelength of the fiber grating has a good linear relationship with the temperature change, and temperature measurement error is less than 0.1 °C, and the accuracy is effectively improved. It can be applied to real-time monitoring of human body temperature in medical treatment.
