Abstract

The invention discloses a three-dimensional pressure sensing fabric with spacer woven structures and a method for preparing the three-dimensional pressure sensing fabric. The three-dimensional pressure sensing fabric comprises upper surface yarn layer and a lower surface yarn layer. The upper surface yarn layer and the lower surface yarn layer are integrally bound with each other by spacing yarns.The method includes weaving the upper surface yarn layer and the lower surface yarn layer by the aid of three-dimensional weaving processes; weaving carbon nano-tube yarns into the upper surface yarnlayer along warp and weft directions and interweaving the carbon nano-tube yarns and the upper surface yarn layer to form conductive networks which are pressure sensing layers; interweaving the uppersurface yarn layer and the lower surface yarn layer with each other by the aid of the spacing yarns to form the three-dimensional pressure sensing fabric which is a three-dimensional spacer sensing fabric. The three-dimensional pressure sensing fabric and the method have the advantages that the three-dimensional pressure sensing fabric with the spacer structures can greatly deform when pressuresare applied to the surfaces of the three-dimensional pressure sensing fabric, the carbon nano-tube yarns in the pressure sensing layers can deform, and accordingly electric resistance can be changed;the three-dimensional pressure sensing fabric is high in sensitivity under the low pressures and is good in recoverability under the high pressures, and the three-dimensional pressure sensing fabric and the method can be widely applied to engineering application and the intelligent wearable field.

Description

technical field [0001] The invention relates to a pressure-sensing fabric with a three-dimensional interval woven structure and a preparation method thereof, belonging to the technical field of pressure-sensing fabrics. Background technique [0002] In recent years, with the increasing demand for smart wearable textiles and the rapid development of sensor technology, textile structure pressure sensors have attracted widespread attention due to their unique advantages. Textile-structured sensors have flexibility, voids, their large deformation capacity, and certain damage tolerance, which allow them to conform to the surface of the human body and provide comfort for applications in wearable electronics. At present, many scholars have studied wearable electronic devices based on textile structures, which can be applied in health treatment, environmental monitoring, screen display, human-computer interaction, energy harvesting, energy storage, wireless communication and other f...
