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 , A is just 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...

Abstract

The invention relates to a smart clothing for human body temperature detection, which includes a broadband light source, a coupler, a distributed fiber grating sensor, an F-P tunable filter, and a packaged integrated circuit part arranged on the clothing. The distributed fiber grating sensor is connected with the F-P tunable filter after the coupler; the integrated circuit part includes a microprocessor, a scanning voltage circuit, a photodetector, a signal conditioning circuit, and the output interface of the microprocessor is connected with the The scanning voltage circuit is connected, the scanning voltage signal generated by the scanning voltage circuit is loaded on the driving end of the F-P tunable filter, the optical signal output by the F-P tunable filter is received by the photodetector, and the electrical signal generated is input through the signal conditioning circuit to the microprocessor. The invention also relates to a method for making the garment. The intelligent clothing of the present invention has the characteristics of lightness of use and can detect the temperature of the human body in real time.

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...
