10. A method according to any one of claims 1 to 9, wherein mixing the conductive polymer, dopant and solvent to form a mixture having a predetermined concentration of the conductive polymer, comprises mixing the conductive polymer, dopant and solvent to form a mixture having 12.5% conductive polymer. 11. A method according to any one of claims 1 to 10, wherein drying the coated fabric comprises drying the coated fabric for at least 30 minutes at 80°C. 12. A sensory textile device comprising: a sensory textile comprising a fabric coated in a conductive polymer and dopant at a predetermined ratio; and a substrate, wherein the sensory textile is attached to the substrate at at least two spaced apart locations and has a rest condition, in which the sensory textile is spaced from the substrate between the at least two spaced apart locations, and a generating condition, in which the sensory textile is in contact with the substrate between the at least two spaced apart locations. 13. A sensory textile device according to claim 12, wherein the sensory textile forms an arch between the at least two spaced apart locations, and stretching the substrate brings the sensory textile into the generating condition. 14. A sensory textile device according to claim 13, wherein the sensory textile forms two or more arches, the two or more arches being attached to the substrate between respective pairs of locations of said at least two spaced apart locations. 15. A sensory textile device according to claim 14, wherein the sensory textile comprises at least two sensory textile portions attached to the substrate in a non-contacting arrangement. 16. A sensory textile device according to any one of claims 12 to 15, being configured to be worn on a finger, the spaced apart locations being on opposite sides of a knuckle of the finger.
