Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) acting as a typical low-cost and widely used polymer and exhibiting excellent conductivity when dissolved in an aqueous solution is deposited with floating-coating method. In addition, this surface improved method proposes a novel concept for sustainable energy devices of TENG. Scanning electron microscopy images showed the surface conditions of the PEDOT:PSS coated wood compared with that of the PEDOT:PSS dip-coated wood. The performance the TENGs containing Al foil and a polyimide friction layer as energy harvester operating in the vertical contact-separation mode are presented. Furthermore, the output voltages of the TENGs monitoring a finger touch are observed as motion sensor operation.</p>
