[ 008 ] Providing a dopant may comprise providing a dopant to improve the conductivity of the conductive polymer once dried on the coated fabric. Providing a dopant may comprise providing dimethyl sulphoxide (DMSO). 

[009] Mixing the conductive polymer, dopant and solvent t o form a mixture having a predetermined ratio of the conductive polymer to dopant, may comprise doping the conductive polymer with 5wt% of the dopant. 

[ 010 ] Providing a solvent may comprise providing water. Providing water may comprise providing deionised water. 

[Oil] Mixing the conductive polymer, dopant and solvent t o form a mixture having a predetermined concentration of the conductive polymer, may comprise mixing the conductive polymer, dopant and solvent to form a mixture having 12.5% conductive polymer. 

[ 012 ] Drying the coated fabric may comprise drying the coated fabric for at least 30 minutes at 80°C. 

[ 013 ] Also disclosed herein is 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. 

[ 014 ] The sensory textile may form an arch between the at least two spaced apart locations, and stretching the substrate brings the sensory textile into the generating condition. The sensory textile may form two or more arches, the two or more arches being attached t o the substrate between respective pairs of locations of said at least two spaced apart locations. Thus, the sensory textile being spaced from the substrate between the at least two spaced apart locations includes the sensory textile being spaced from the substrate over the length of the sensory textile between the two spaced apart locations and, in embodiments such as those incorporating two or more arches, the sensory textile being spaced from the substrate at various parts of its length between the at least two spaced apart locations. In alternative embodiments, arches of a continuous piece of sensory textile may be considered to be spaced from the substrate, with two of the at least two spaced apart locations being between the arch and a neighbouring arch and/or between the arch and the end of the continuous piece.
