Flexible wearable optical fiber sensor and human dynamic whole body distributed monitoring method

Abstract

The invention discloses a flexible wearable optical fiber sensor and a human dynamic whole body distributed monitoring method. A human dynamic whole body monitoring system comprises a demodulator, a host computer, and a plurality of the flexible wearable optical fiber sensors, wherein the flexible wearable optical fiber sensor is composed of a flexible bending optical fiber module, a first fiber Bragg grating, a second fiber Bragg grating and a fiber Bragg grating protection structure. The fiber Bragg grating wavelength division multiplexing technology is used, the plurality of the flexible wearable optical fiber sensors are connected in series and fixed to a user's body through Velcro and elastic bands, and the user's movement status, including a joint bending angle, a muscle stretching amount, a respiration rate and other physiological parameters, is monitored. The recognition of stretching and bending degrees is realized by detecting the change of the light intensity corresponding to an fiber Bragg grating spectral signal center wavelength, physiological parameters such as a joint bending angle, a muscle stretching amount and a respiration rate are monitored in real time when the human body is active, high precision and sensitivity are achieved, and the flexible wearable optical fiber sensor has a simple structure, and can be worn freely without affecting the user's movementfreedom degree.

Description

technical field [0001] The invention belongs to the related fields of sensor technology, wearable equipment, etc., and in particular relates to a flexible and wearable optical fiber sensor and a distributed monitoring method for human dynamic whole body. Background technique [0002] In recent years, with the acceleration of the pace of social life and the irregular work and rest of people, a large number of people are in a sub-health state, which leads to a decrease in people's immunity and an increase in the probability of disease. The movement monitoring of the human body can obtain many physiological parameters such as joint bending angle, muscle stretching amount, and breathing rate in real time during human activities, and provide raw data for disease prevention and making reasonable exercise plans and methods, and can also provide doctors with Data technology support is provided for the treatment of patients and the formulation of follow-up rehabilitation training pla...

Problems solved by technology

[0003] At present, many scholars in the domestic and foreign industries and academic circles have proposed such as electromagnetic, mechanical, and optical motion monitoring sensors to monitor human body activity parameters, but these monitoring systems are large in size and hinder the user's movement. Disadvantages such as inability to monitor the body shape of the human body
