“…Moreover, the maximum output power was equivalent to a power density of 148.8 nW/cm². The power density produced by PENGs with Co-doped ZnO NFs was greater than the achieved by a previous study, namely 51.7 nW/cm 2 (Suyitno et al, 2014b).…”

“…The PENGs with Ga-doped ZnO NWs produced a higher voltage ranging from 120 to 560 mV (Zhao et al, 2015b) if compared with undoped ZnO NWs generated a lower voltage of up to 25 mV (Wang et al, 2008). Meanwhile, PENGs fabricated from Al-doped ZnO NRs and NFs capable of generating a voltage up to 60 mV (Fang and Kang, 2010) and 265.5 mV (Suyitno et al, 2014b), respectively. However, the voltage and power density of PENGs with ZnO nanomaterials are still low (Ren et al, 2009;Kanjwal et al, 2011).…”

The ferromagnetic cobalt doped into Zinc Oxide (ZnO) crystals is a promising method for enhancing the performance of PiezoelectricBased Nano Generators (PENGs). The study reports the characterization and testing PENGs which simply fabricated from cobalt-doped ZnO nanofibers (NFs) synthesized by electro spinning machine. The electro spinning processes were conducted at a flow rate of 4 µL/min and at various cobalt concentrations followed by sintering at a temperature of 500°C. The X-Ray Diffraction (XRD) spectra demonstrate that the crystalline diameter of Co-doped ZnO NFs increased as the content of cobalt increased, up to a concentration of 9%. Meanwhile, the maximum output voltage and power density of PENGs with Co-doped ZnO NFs were 221.6 mV and 148.8 nW/cm 2 , respectively when the PENGs were subjected to a cyclic mechanical load of 0.5 kg. Therefore, PENGs fabricated from Co-doped ZnO NFs are challenging for the next generation of self-powered devices.

“…However, the co-doping Co:Al = 75:25 was able to produce the highest output power of 218 nW/cm². The output power of the ZnO fibers-based nanogenerators co-doped with Co:Al was far greater than previous study at 51.7 nW/cm² [4]. In line with the property piezoelectric material, d33, the co-doping Co:Al of 75:25 was able to provide the increased output power.…”

“…Doping aluminum into ZnO material, for example, is aimed for producing a small diameter of nano fibers [3]. Doping aluminum of ZnO nanofibers did not only halt the fiber growth, but also significantly increase the voltage of nanogenerators [4]. Meanwhile, doping cobalt increases the elastic modulus of nano fibers [5].…”

The effect of heating temperature in static thermal tensioning (STT) welding on mechanical properties and fatigue crack propagation rate of FCAW in steel A 36 AIP Conference Proceedings 1788, 030057 (2017) Abstract. This study reports the effect of co-doping cobalt and aluminum on the properties of ZnO-fiber piezoelectric materials. Synthesizing the ZnO-fiber piezoelectric material consisted of four steps: (1) making precursor solutions by doping aluminum and cobalt, (2) creating green fibers with an electrospinning machine, (3) sintering the fibers, and (4) testing the piezoelectricity properties. The precursor materials used were polyvinyl acetate (PVA), zinc-acetate (ZnAc), AlCl3, and CoAc. The ZnO fibers were produced in an electrospinning machine with a distance between needle tip and collector of 8 cm and a flow rate of precursor solutions at 4 μL/min. The sintering was conducted at temperatures of 400, 450, 500, 550, and 600°C for 4 hours. Piezotest was used to measure the piezoelectricity properties of ZnO or d33. The results show that the maximum value of d33 was obtained in co-doping cobalt:aluminum at a ratio of 75:25 at the sintering temperature of 500°C, which amounted to -4.1 pC/N. The ZnO-fiber-based nanogenerators co-doped with cobalt and aluminum was capable of producing energy by 218 nW/cm².

In this research paper we present a comparative study on the enhanced piezoelectric performance between Carbon Nanotubes (CNT)/PVDF nanocomposite as well as Iron-Reduced Graphene Oxide (Fe-RGO)/PVDF nanocomposite. The enhanced performance is realized by a unique device structure, in which the bottom electrode is physically not in contact with the piezoelectric film until external excitation is applied. FTIR characterization shows the enhancement of polar crystallization phases due to electrostatic interactions in PVDF by the addition of CNT and Fe-RGO. Raman Spectroscopy indicates the formation of good quality Fe-RGO nanosheets and also shows high crystalline quality of CNTs. Raman Spectroscopy identifies the interaction between CNTs and Fe-RGO nanosheets with the polymer that supports the piezoelectric current generation mechanism. Conductivity measurements show that addition of CNT and Fe-RGO in PVDF increases the conductivity of the nanocomposite films. The CNT/PVDF and Fe-RGO/PVDF piezoelectric energy harvesting device produced an open circuit output voltage of 2.5 V and 1.2 V respectively. A short circuit rectified current of nearly 700 nA and 300 nA was detected by the CNT/PVDF and Fe-RGO/PVDF based piezoelectric energy harvesting device.
