Abstract
On the basis of a vertically aligned ultralong Pb(Zr<sub>0.52</sub>Ti<sub>0.48</sub>)O<sub>3</sub> (PZT) nanowire array fabricated
using
electrospinning nanofibers, we developed a new type of integrated
nanogenerator (NG) with ultrahigh output voltage of 209 V and current
density of 23.5 μA/cm<sup>2</sup>, which are 3.6 times and 2.9
times of the previous record values, respectively. The output electricity
can be directly used to stimulate the frog’s sciatic nerve
and to induce a contraction of a frog’s gastrocnemius. The
NG can instantaneously power a commercial light-emitting diode (LED)
without the energy storage process
