Schematic diagram and power generation for the LiNbO3-PDMS composite nanogenerator. Schematic diagram of the LiNbO3-PDMS composite nanogenerator for (a)e33 and (c)e31 geometries. Dark brown, yellow, and light blue represent the Kapton film, Au/Cr electrode, and PS film, respectively. The rainbow color of the LiNbO3 nanowires represents the piezoelectric potential after the stress application. The open-circuit voltage (V) and closed-circuit current (I) at selected strains for (b)e33 and (d)e31 geometries.
