Problems solved by technology
[0003] The development and research of smart clothing originated in the late 1970s. At that time, electronic technology was still relatively backward, so the development of smart clothing was also very slow. It was bulky and cumbersome, and had a single function.

Embodiment Construction
[0033] The following first introduces the working principle and working process of the distributed fiber grating sensor.
[0034] The structure and working principle of fiber grating sensors have been described in many documents. According to the coupled-mode theory of fiber Bragg gratings, a uniform non-blazed fiber Bragg grating can couple one guided mode transmitted in it to another guided mode transmitted in the opposite direction to form narrow-band reflection, and the peak reflection Bragg wavelength λ B for
[0035] lambda B =2n eff Λ
[0036] where n eff is the effective refractive index of the guided mode, and Λ is the grating period.
[0037] cause lambda B There are many factors of drift, if only the influence of temperature T is considered, then λ B , n eff , Λ is only a function of T. Temperature changes lead to thermal expansion and contraction of fiber gratings and changes in refractive index, and the Bragg wavelength shifts they produce can be recorded...

The invention also relates to the making method of the garment. The smart garment has the advantages of portable use and real-time detection for the body temperature.
Description
technical field [0001] The invention belongs to the technical field of smart clothing, and relates to a smart clothing for detecting human body temperature. Background technique [0002] Smart clothing is a new field, which is the product of the combination and intersection of microelectronics technology, new sensor technology, modern communication technology, intelligent control technology, textile technology and other related new technologies. Smart clothing can not only perceive changes in the external environment or internal state, but also respond to such changes in real time through a feedback mechanism. Perception, feedback and reaction are the three major elements of smart clothing. In addition, it has the characteristics of light wear and real-time monitoring. It can be widely used in medical and health, military and aerospace, entertainment and communication, safety and security and other fields. It has a very broad application prospects. [0003] The development...
