On the basis of a vertically aligned ultralong Pb(Zr0.52Ti0.48)O3 (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 渭A/cm2, 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鈥檚 sciatic nerve and to induce a contraction of a frog鈥檚 gastrocnemius. The NG can instantaneously power a commercial light-emitting diode (LED) without the energy storage process.
