Abstract

The invention relates to a flexible fabric pressure and strain composite sensor, which is characterized in that it comprises an upper conductive layer fabric, an insulating layer fabric and a lower conductive layer fabric stacked sequentially from top to bottom, and the upper conductive layer fabric and the lower conductive layer fabric The fabrics are all woven with metal-plated conductive yarns as weft yarns and elastic yarns as warp yarns, and the insulating layer fabric is woven with non-conductive yarns as weft yarns and non-conductive elastic yarns as warp yarns. The first layer fabric, the insulating layer fabric and the lower conductive layer fabric are connected as a whole by changing the inner and outer three layers at the two ends of the warp yarn, and the end of the metal-plated conductive yarn is used as the electrode of the flexible fabric pressure and strain composite sensor lead. The invention effectively improves the structural stability of the existing capacitive fabric sensor, is conducive to rapid large-scale preparation, and can not only realize the detection of pressure, but also realize the detection of strain.

Description

technical field [0001] The invention relates to a flexible fabric pressure and strain composite sensor, which belongs to the technical field of textile and flexible electronics. Background technique [0002] Compared with traditional rigid sensors, flexible sensors have the advantages of deformability, strong size adaptability, and good human-computer interaction. With the rapid development of wearable technology and robot technology, flexible fabric sensors are made by embedding or integrating flexible sensors into soft, lightweight, breathable, stretchable and bendable fabrics, which can conform to the body of the wearer or robot, It can be applied in human motion monitoring, soft robot skin, medical physiological signal monitoring and human-computer interaction and other fields. [0003] Fabric sensors are mainly divided into resistive and capacitive according to their sensing principles. Among them, the resistive fabric sensor measures the force or strain based on the ...
