摘要：

Ultra-long and flexible single-crystalline lead zirconate titanate Pb(Zr0.52Ti0.48)O-3 (PZT) nano/ micro-wires (N/MWs) were synthesized via a hydrothermal method. Owing to the self-polarization effect of the as-synthesized PZT N/MWs, the N/MWs can be used to directly fabricate a nanogenerator (NG) without being poled under electric field. Using such an NG, we demonstrated a flexible, self-powered system for detecting UV irradiance by utilizing the cycled contraction-expansion of a flexible rubber membrane. (C) 2012 Elsevier Ltd.
