Abstract We report a technique to construct a vertically integrated nanogenerator (VI‐NG) based on ZnO nanowire (NW) arrays. The VI‐NG consists of nine single NGs connected mixed parallel and serial by a layer‐by‐layer stacking. For the single layer NG, the peak output voltage and current are 0.045 V and 2.5 nA, respectively. The VI‐NG produces an output power density of 2.8 nW/cm 2 with a peak output voltage of 0.15 V and output current of 7.2 nA. The vertical integration of the multi‐NG provides a feasible technique for effectively converting mechanical energies to electricity from environment. (© 2011 WILEY‐VCH Verlag GmbH & Co.
