conductive polymer are mixed at a predetermined ratio, and with a predetermined concentration of the conductive polymer. 

[042] Step 106 involves coating the fabric with the conductive polymer and dopant, by contacting the fabric with the mixture formed by step 104. 

[043] Step 108 may involve drying at a particular temperature, or under specific conditions to yield the sensory textiles described herein. Or may involve air drying. This step is discussed below in more detail. 

[044] The conductive polymer may be provided in step 102 as a dispersion in a solution. Thus, the ratio may be the ratio of dopant t o conductive polymer solution, and the concentration may be a concentration of the conductive polymer solution. Moreover, the conductive polymer may be a conductive organic polymer. 

[045] Before the coating process, and before, after or as the conductive polymer solution is mixed with the solvent, as-purchased conductive polymer solution (e.g. PEDOT:PSS solution or other solution that is stable in air) may be doped with a dopant per step 104. The dopant may improve the conductivity of the conductive polymer solution once dried on the coated fabric (i.e. the conductive polymer derived from the solution), per Step 108. 

[046] Mixing the dopant with the conductive polymer solution per Step 104 may involve mixing demthyl sulphoxide (DMSO) with the conductive polymer solution. The mixture may be 5wt% of dopant (e.g. (DMSO)) solution t o improve its conductivity. The doped PEDOT:PSS solution, or doped conductive polymer, may then be diluted by different ratios of the solvent to determine optimum dilution - for example, 12.5% conductive polymer. After dilution, a fabric - e.g. pure cotton textile - is contacted with the mixture - per Step 106 - by being immersed in the mixture or coating solution for a predetermined period of time - e.g. 10 minutes - for full absorption. The solvent may be, for example, water (e.g. deionised (Dl) water). 

[047] The wet or coated textile may then be dried - e.g. by placing the coated textile into an oven and baked for at least 30 minutes at 80°C,or a temperature at which the dopant is not removed - until fully dried, per Step 108. It will be appreciated that various drying conditions may suit different types of solvent, conductive polymer or dopant, and the drying Step 108 may be adjusted accordingly, without departing from the scope of the present disclosure. 

[048] Thus, with reference t o FIG. 2, a sensory textile device 200 can be produced comprising a fabric coated in a conductive polymer and dopant 202. The sensory textile device 200 also comprises a substrate which may be silicon rubber as indicated by reference numeral
