wearable smart devices - having good film forming ability, high electrical conductivity, intrinsically high work function and good physical and chemical stability in air. [035] Although PEDOT:PSS is a flexible polymer, it is not stretchable intrinsically. With the aid of chemical enhancers which change morphology and act as conductivity-enhancing dopants, PEDOT:PSS can be stretched up to 100% with a minor decrease in conductivity. [036] Through incorporation with stretchable textile substrates, the PEDOT:PSS textile composited film is also able to be stretched to 80% while maintaining its electrical conductivity. [037] In accordance with the present disclosure, a facile and low-cost approach to fabricate a smart textile, interchangeably referred to as a sensory textile, is disclosed. The smart textile may be used for both energy harvesting and sensing. [038] A fabric used as the substrate for the sensory textile may be, for example, a 100% cotton textile owing to its advantages of being soft, light, tough, breathable, and easily available in the market. The smart textile can be easily fabricated through coating the cotton textile with PEDOT:PSS solution as shown in Fig. 2b, with FIG. 2 shows (a) applications of PEDOT:PSS coated smart textile, (b) SEM image of coated textile, and (c) working mechanism of triboelectric nanogenerator for smart textile. [039] A method 100 for forming a sensory textile is set out in the flow diagram of FIG. 1, and is reflected in the textile shown in FIG. 2b. The method 100 for forming a sensory textile broadly comprises the steps of: Step 102: providing a conductive polymer, a dopant and a solvent; Step 104: mixing the conductive polymer, dopant and solvent; Step 106: contacting a fabric with the mixture formed by step 104; and Step 108: drying the coated fabric. t o 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 t o coat the fabric with the conductive polymer and dopant; and drying the coated fabric. [040] Step 102 is self-explanatory, and example compounds for the polymer, dopant and solvent are discussed below. [041] Step 104 involves forming a mixture. To achieve the electromechanical properties of the sensory textile, particularly triboelectric properties in some embodiments, the dopant and
