Multifunctional sensing integrated flexible fabric-based sensor and application thereof

Abstract

The invention provides a multifunctional sensing integrated flexible fabric-based sensor and application thereof. The multifunctional sensing integrated flexible fabric-based sensor is obtained by interweaving and integrating three sets of mutually independent warp yarn and weft yarn systems through a weaving technology, wherein the three sets of mutually independent warp yarn and weft yarn systems are respectively formed by three kinds of yarns with different sensing functions; the three sets of mutually independent warp and weft systems are respectively a warp and weft system formed by yarns with a pressure sensing function, a warp and weft system formed by yarns with a temperature sensing function and a warp and weft system formed by yarns with a humidity sensing function. The multifunctional sensor is constructed from three structural dimensions of fiber, yarn and fabric, is used for realizing a large-area accurate sensing function of pressure, temperature and humidity, has excellent flexibility and anti-interference performance, and can accurately and independently sense different signals and integrate the signals through anti-interference processing. The sensor has a huge application prospect in the fields of wearable flexible electronic devices and the like.

Description

technical field [0001] The invention relates to the technical field of flexible sensor preparation, in particular to a flexible fabric-based sensor with multifunctional sensor integration and its application. Background technique [0002] Wearable flexible electronic devices, because of their flexibility, light weight, low cost, and portability, are widely used in many fields such as real-time monitoring of human movement and health, and human-computer interaction. However, there are still problems such as low sensitivity and response speed, high detection limit, and narrow detection range, and the basic performance of the device still needs to be improved. In the actual application process, there are also challenges such as stability, low ability to resist environmental interference, and difficulty in large-scale production. To solve these problems, designing and manufacturing a material system with excellent performance and multifunctional sensor integration and a reasona...

AI Technical Summary

Problems solved by technology

However, the sensor has a defect of single function. The sensor does not take into account the interference of the signal caused by the volume change of the material caused by the temperature, that is, the temperature will greatly interfere with the accuracy of the detected pressure signal.

In addition, the sensor has not been treated with fabric hydrophobicity, so it cannot meet the complex working environment of the sensor for a long time

Therefore, the effect of the sensor will be greatly reduced in real application scenarios where the temperature and humidity change significantly for a long time.
