We have synthesized BaTiO3 nanowires (NWs) via a simple hydrothermal method at low temperature and developed a lead-free, flexible nanocomposite generator (NCG) device by a simple, low-cost, and scalable spin-coating method. The hydrothermally grown BaTiO3 NWs are mixed in a polymer matrix without a toxic dispersion enhancer to produce a piezoelectric nanocomposite (p-NC). During periodical and regular bending and unbending motions, the NCG device fabricated by utilizing a BaTiO3 NWs-polydimethylsiloxane (PDMS) composite successfully harvests the output voltage of similar to 7.0 V and current signals of similar to 360 nA, which are utilized to drive a liquid crystal display (LCD). We also characterized the instantaneous power (similar to 1.2 mu W) of the NCG device by calculating the load voltage and current through the connected external resistance.
