Research on body temperature detection in smart clothing based on novel FBG sensor

Body temperature is one of the most basic physiological parameters of the human body, and real-time monitoring of body temperature can help us to understand the human body's disease conditions and provide timely solutions for patients to save their lives. In this paper, a wearable Fiber Bragg Grating (FBG) sensor based on a wearable sensor to achieve smart clothing temperature measurement system researched, to achieve non-contact body temperature detection. The sensor is encapsulated in an aluminium tube with good expansibility and stability, and then implanted into the armpit parts of the smart clothing without damaging the FBG, The clothing become a truly wearable "fabric sensor" whose comfort is improved and the body temperature can be accurately measured at the same time. The experimental results show that the different between the measured data and the real data is within ±0.3°C.
