We report a novel self-powered nanocomposite sensor composed of K0:5Na0:5Nb O3(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.
