Flexible Nanogenerator Based on Single BaTiO<SUB>3</SUB> Nanowire

Abstract

Using ferroelectric materials which exhibit the combination of large piezoelectric coefficients and good flexibilities as nanogererator is desirable for improving the electric output. In this work, a flexible nanogenerator based on single BaTiO 3 nanowire is described. The flexible nanogenerator can generate an output voltage of up to 0.21 V and current of 1.3 nA by periodically bending and releasing the substrate. The electric outputs were found to be proportional to the strain and strain rate. Furthermore, the electric output was enhanced by connecting two generators in series and in parallel with the correct polarity and sequence. Therefore, the flexible nanogenerator demonstrates the energy harvesting using BaTiO 3 nanowires and the increase of the output electricity through integration of BaTiO 3 nanowires.

One-Step Solvent Evaporation-Assisted 3D Printing of Piezoelectric PVDF Nanocomposite Structures

“…[9][10] Fillers like carbon nanotubes, [11][12] clay, 13 cellulose, 10 magnetic 14 and piezoelectric nanoparticles (NPs) 15 have proven to be very efficient in preventing the reversion of β-phase to α-phase upon solidification. Addition of eco-friendly and biocompatible [16][17] piezoelectric ceramic filler -barium-titanate (BaTiO3 NPs) [18][19][20][21][22] into PVDF has also shown to improve the ferro-and piezoelectric properties of PVDF without compromising its flexibility or strength. The incorporation of BaTiO3 NPs into PVDF has been attempted so far via sonication 21,[23][24] and ball-milling [25][26] approaches.…”

A review on piezoelectric fibers and nanowires for energy harvesting

“…Energy harvesting from piezoelectric ceramic nanofibers and NWs: Piezoelectric ceramic nanofibers and NWs show high piezoelectrical outputs [28,100,101]. Perovskitestructured ceramic NWs, including (BaTiO 3 [102], PbZr x Ti 1-x O 3 [103], and (1-x)Pb(Mg 1/3 Nb 2/3 )O 3 -xPbTiO 3 (PMN-PT) [104]), and wurtzite-structured ceramic NWs (ZnO [28], GaN [105], ZnS [106], and CdS [107]) have been integrated into NGs over the last 10 years. The NW-based energy-harvesting technology has taken hold the attention of researchers due to their great advantages, including large surface area, robust mechanical properties, almost free of dislocations, deformation under a very small applied force, and extraordinary sensitivity to characteristically small ambient vibrations [108,109].…”

Simulation study on piezoelectric characteristics of two‐dimensional ZnO nanodiscs

“…Over the past few years, researchers have made valid progress in NGs by using various kinds of piezoelectric materials, such as zinc oxide (ZnO), gallium nitride, cadium sulphide, lead zirconate titanate and barium titanate [8,[14][15][16][17][18]. Among these materials, ZnO has been recognised as the potential material for piezoelectric NGs due to the desirable semiconducting, piezoelectric and environmental-friendly properties.…”
