Abstract

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 ∼7.0 V and current signals of ∼360 nA, which are utilized to drive a liquid crystal display (LCD). We also characterized the instantaneous power (∼1.2 μW) of the NCG device by calculating the load voltage and current through the connected external resistance. This journal is
