Paper-Based ZnO Nanogenerator Using Contact Electrification and Piezoelectric Effects.

In this letter, we present a ZnO nanogenerator built on a paper substrate producing electricity using both contact electrification and piezoelectric effects. Paper is an environmentally friendly material and can help to improve the performance of the ZnO nanogenerator due to its natural roughness. The nanogenerator produced a maximum peak voltag of 38.4 V and a maximum peak current density of 3.2 \mu \textA /cm ^2 from both the inherent piezoelectric property of ZnO and contact electrification between poly(methyl methacrylate) and ZnO nanostructures.
