In this paper, we present a tandem-type vertically integrated nanogenerator (TYING) device with five layers of alternately stacked thin films (AlN/ZnO/AlN/ZnO/AlN). The TYING device shows about twice larger output voltages than the conventional VING device with three layers of stacked thin films (AlN/ZnO/AlN). Moreover, the TYING device can be fabricated in a tandem-type structure simply through the vertical integration of two similar VING devices. This device will be usefully applied for biocompatible micro-energy harvesting systems.
