A piezoelectric nanogenerator (PNG) device consisting of conducting polymer and AgNWs as an electrode using poly(vinylidene fluoride) (PVDF) as an active layer is demonstrated. Here, a poly(3,4-ethylenedioxythiophene) (PEDOT) derivative, poly(2-hexyl-2,3-dihydrothieno[3,4-b][1,4]dioxine:dodecyl sulfate (PEDOT-C6:DS) was synthesized. This PNG exhibit superior energy harvesting performance with maximum piezoelectric output voltage and current 7.02 V and 1.11 μA, at 8 Hz operating frequency, respectively. The fabricated hybrid electrode PNG (1.5 cmx2.5 cm) generates a maximum output power of 1.18 µW. The fabricated PNG device is capable to lit up white LEDs and charged a commercial capacitor of 1 µF with charged voltage 2.68 V in 80 s. Further, with the results obtained it is confirmed that the PEDOT-C6:DS is a promising material for hybrid electrodes in electronic applications. |
