摘要：

A novel approach to fabricate a high performance flexible piezoelectric nanogenerator (PNG) by employing K0.5Na0.5NbO3 (KNN)/PDMS/C composite thin film has been proposed. The formed 12wt% C doping KNN/PDMS PNG demonstrates a higher relative permittivity (?(r), 173.56) and larger remanent polarization (P-r, 1.84 mu C/cm(2)) than pure KNN/PDMS film, thus serving as the possible origins of their comparative piezoelectric activities, which could generate an maximum output voltage of 10.55V (3.3 times as much as the PNG without C doping). Besides, the PNG is able to light up a commercial green light-emitting diode (LED) through an energy storage capacitor (47 mu F), showing its great potential as power of wearable and mobile devices.
