摘要：

We have developed a simple, cost-effective, and scalable approach to fabricate a piezoelectric nanogenerator (NG) with stretchable and flexible characteristics using BaTiO3 nanotubes, which were synthesized by the hydrothermal method. The NG was fabricated by making a composite of the nanotubes with polymer poly(dimethylsiloxane) (PDMS). The peak open-circuit voltage and short-circuit current of the NG reached a high level of 5.5 V and 350 nA (current density of 350 nA/cm(2)), respectively. It was used to directly drive a commercial liquid crystal display. The BaTiO3 nanotubes/PDMS composite is highly transparent and useful for a large-scale (11 x 11 cm) fabrication of lead-free piezoelectric NG.
