Abstract
Using ferroelectric materials which exhibit the combination of large piezoelectric coefficients and good flexibilities as nanogererator is desirable for improving the electric output. In this work, a flexible nanogenerator based on single BaTiO3 nanowire is described. The flexible nanogenerator can generate an output voltage of up to 0.21 V and current of 1.3 nA by periodically bending and releasing the substrate. The electric outputs were found to be proportional to the strain and strain rate. Furthermore, the electric output was enhanced by connecting two generators in series and in parallel with the correct polarity and sequence. Therefore, the flexible nanogenerator demonstrates the energy harvesting using BaTiO3 nanowires and the increase of the output electricity through integration of BaTiO3 nanowires.
