“…Mechanical energy is then converted into electrical energy as shown in Figure 5(d). [33][34][35] Figure 5(e) shows the current-voltage (I-V) characteristics of ZnO NWs synthesized on CNT coated non-conductive textile fabric substrate (S1). Figure 5(f) shows the current-voltage (I-V) characteristics of the as grown ZnO NWs on conductive textile fabric substrate (S2) and Figure 5(g) shows the I-V characteristics of ZnO NWs grown on the CNTs film coated conductive textile fabric substrate (S3).…”

In the present work, three junctions were fabricated on textile fabric as an alternative substrate for harvesting piezoelectric potential. First junction was formed on ordinary textile as (textile/multi-walled carbon nanotube film/zinc oxide nanowires (S1: T/CNTs/ZnO NWs)) and the other two were formed on conductive textile with the following layer sequence: conductive textile/zinc oxide nanowires (S2: CT/ZnO NWs) and conductive textile/multi-walled carbon nanotubes film/zinc oxide nanowires (S3: CT/CNTs/ZnO NWs). Piezoelectric potential was harvested by using atomic force microscopy in contact mode for the comparative analysis of the generated piezoelectric potential. ZnO NWs were synthesized by using the aqueous chemical growth method. Surface analysis of the grown nanostructures was performed by using scanning electron microscopy and transmission electron microscopy. The growth orientation and crystalline size were studied by using X-ray diffraction technique. This study reveals that textile as an alternative substrate have many features like cost effective, highly flexible, nontoxic, light weight, soft, recyclable, reproducible, portable, wearable, and washable for nanogenerators fabrication with acceptable performance and with a wide choice of modification for obtaining large amount of piezoelectric potential

“…The surface potential of a bent ZnO nanowire was measured to be in the range of 50 mV to 80 mV by Kelvin probe force microscopy [250]. Tip abrasion after scanning for long times reduced the magnitude of the output signals [537,538], and this could be mitigated by diamond coating [539].…”

One-dimensional ZnO nanostructures: Solution growth and functional properties

2011

View full text Add to dashboard Cite

One-dimensional (1D) ZnO nanostructures have been studied intensively and extensively over the last decade not only for their remarkable chemical and physical properties, but also for their current and future diverse technological applications. This article gives a comprehensive overview of the progress that has been made within the context of 1D ZnO nanostructures synthesized via wet chemical methods. We will cover the synthetic methodologies and corresponding growth mechanisms, different structures, doping and alloying, positioncontrolled growth on substrates, and finally, their functional properties as catalysts, hydrophobic surfaces, sensors, and in nanoelectronic, optical, optoelectronic, and energy harvesting devices.

“…The development of a nanogenerator to convert energy from the environment into electric energy would facilitate the development of self-powered systems relying on nanodevices. In recent years, various articles have reported the utilization of the piezoelectric properties of zinc oxide (ZnO) nanostructures, but most of these efforts have focused on studying single ZnO nanowire (NW) [3,4]. A few investigations have discussed ZnO nanowire arrays with glass, sapphire, Si, or other hard substrates [3][4][5].…”

We here, present a flexible handwriting driven nanogenerator (NG) based on zinc oxide (ZnO) nanowires (NWs)/polymer composite grown/deposited on paper substrate. The targeted configuration is composed of ZnO NWs/PVDF polymer ink pasted and sandwiched between two pieces of paper with ZnO NWs grown chemically on one side of each piece of paper.Other configurations utilizing a ZnO/PVDF ink with different ZnO morphology on paper platform and others on plastic platform were fabricated for comparison. The mechanical pressure exerted on the paper platform while handwriting is then harvested by the ZnO NWs/polymer based NG to deliver electrical energy. Two handwriting modes were tested; these were slow (low pressure) and fast (high pressure) handwriting. The maximum achieved harvested open circuit voltage was 4.8 V. While an out power density as high as 1.3 mW/mm 2 was estimated when connecting the NG to a 100 Ω load resistor. The observed results were stable and reproducible. The present NG provides a low cost and scalable approach with many potential applications, like e.g. programmable paper for signature verification.
