Piezoelectric nanogenerator, harvesting energy from mechanical actions in our living environments, holds great promise to power sustainable self-sufficient micro/nano-systems and mobile/portable electronics. In this work, a flexible nanogenerator was fabricated by applying polydimethylsiloxane (PDMS) elastomer directly on BaTiO3 nanowire and following curing technique. The BaTiO3 nanowire was prepared by electrospinning and calcining processes, and its structure and morphology was characterized by scanning electron microscopy and X-ray diffraction method. After poling the flexible BaTiO3/PDMS nanogenerator under high electric field at room temperature, time-dependent changes of open-circuit voltage, short-circuit current and power density for the nanogenerator were investigated. The research implies the feasibility and efficiency of BaTiO3 nanowire based flexible nanogenerator for wearable self-powered systems. |
