Piezoelectric-Induced Triboelectric Hybrid Nanogenerators Based on the ZnO Nanowire Layer Decorated on the Au/polydimethylsiloxane–Al Structure for Enhanced Triboelectric Performance
Here, we demonstrate
a novel device structure design to enhance the electrical conversion
output of a triboelectric device through the piezoelectric effect
called as the piezo-induced triboelectric (PIT) device. By utilizing
the piezopotential of ZnO nanowires embedded into the polydimethylsiloxane
(PDMS) layer attached on the top electrode of the conventional triboelectric
device (Au/PDMS–Al), the PIT device exhibits an output power
density of 50 μW/cm<sup>2</sup>, which is larger than that of
the conventional triboelectric device by up to 100 folds under the
external applied force of 8.5 N. We found that the effect of the external
piezopotential on the top Au electrode of the triboelectric device
not only enhances the electron transfer from the Al electrode to PDMS
but also boosts the internal built-in potential of the triboelectric
device through an external electric field of the piezoelectric layer.
Furthermore, 100 light-emitting diodes (LEDs) could be lighted up
via the PIT device, whereas the conventional device could illuminate
less than 20 LED bulbs. Thus, our results highlight that the enhancement
of the triboelectric output can be achieved by using a PIT device
structure, which enables us to develop hybrid nanogenerators for various
self-power electronics such as wearable and mobile devices
