Abstract: A triboelectric sensor comprises a substrate; at least one grid structure disposed in or on the substrate; and at least one electrode for collecting triboelectric charges that are generated by sliding of an object over a surface of the substrate; wherein the at least one grid structure is configured such that motion of the object is detectable from a signal generated by crossing of the object over at least part of the grid structure.

Abstract: Disclosed is a sensory flooring system. The flooring system comprises a plurality of flooring segments and, for each flooring segment, one or more electrode portions. Each electrode portion is responsive to a force applied to the flooring segment and at least one electrode portion of a said flooring segment forms an electrode with at least one electrode portion of another said flooring segment. Moreover, each flooring segment comprises a unique encoding of the one or more electrode portions. Also disclosed is a sensory floor such a sensory flooring system, a receiver for receiving an electrical output from the one or more electrodes formed by said one or more electrode portions of the flooring segments, and a processor for analysing the electrical output and identifying the flooring segment by which the electrical output was produced.

Abstract: Disclosed is a method for forming a sensory textile. The method includes: providing a conductive polymer, a dopant and a solvent; mixing the conductive polymer, dopant and solvent to form a mixture having a predetermined ratio of the conductive polymer and the dopant, and a predetermined concentration of the conductive polymer; contacting a fabric with the mixture to coat the fabric with the conductive polymer and dopant; and drying the coated fabric. Also disclosed is a sensory textile device that includes such a sensory textile, a conductive backing layer and a spacer layer disposed between the sensory textile and conductive backing layer.
