ABSTRACT
Herein, we demonstrate that a flexible, air-permeable, thermoelectric (TE) power generator can be prepared by applying a TE polymer (e.g. poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate)) coated commercial fabric and subsequently by linking the coated strips with a conductive connection (e.g. using fine metal wires). The poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) coated fabric shows very stable TE properties from 300 K to 390 K. The fabric device can generate a TE voltage output (V) of 4.3 mV at a temperature difference (ΔT) of 75.2 K. The potential for using fabric TE devices to harvest body temperature energy has been discussed. Fabric-based TE devices may be useful for the development of new power generating clothing and self-powered wearable electronics.

Mentions: Figure 1a shows the chemical structure of PEDOT:PSS. Figures 1b & c show the SEM image and photo of polyester fabric after the PEDOT:PSS coating treatment. The coated fabric maintained the excellent flexibility and softness of the polyester fabric, which can be easily rolled up, bent, twisted and tailored into any desired shape (Supplementary Fig. S1). It is interesting to note that after the coating treatment, the air permeability of the polyester fabric increased from 30.70 ± 1.10 cm3/cm2/s to 47.67 ± 1.73 cm3/cm2/s. The increased air permeability might be explained by the fact that PEDOT:PSS coating compresses the yarns in fabric to some extent. These results suggest that the PEDOT:PSS coating has no negative effect on the breathable feature of the fabric.
