Abstract: Existing pressure sensing fabrics may involve two portions, i.e., insulating and conductive portions in the fabric, which increases the complexity of the fabric system and more important, and the instablization of the resistance-strain relationship during dynamic deformation which limits the application fields due to intrinsic properties difference between the two portions. These fabrics commonly employ two or more layers to accomplish the detecting functions. Such arrangements increase the thickness, weight, and cost of the sensors with some other disadvantages such as low accuracy, instability, etc. This invention describes a pressure sensing fabric have a general structure as simple as a plurality of electrically conducting yarns forming interlocking loops of yarns. The pressure sensing fabric is found not only be able to sense pressure but also the magnitude of the pressure.
