Abstract :
We report a novel self-powered nanocomposite sensor composed of K inf 0.5 /inf Na inf 0.5 /inf NbO inf 3 /inf (KNN) nanoparticles (NPs) and multiwalled carbon nanotubes (MW-CNTs). The KNN NPs and MW-CNTs are dispersed in polydimethylsioxane by mechanical agitation to produce a piezoelectric nanocomposite device. The device exhibits an output voltage of approximately 30 V and output current of approximately 15 μA. Furthermore,the device exhibits potential as a self-powered pressure sensor because the output voltage can be tested to detect the pressure applied to the device and does not require other sources. © 1996-2012 Tsinghua University Press.
