摘要:	摘要： In this paper, we demonstrated a highly-flexible all-fiber based transparent piezoelectric harvester (ATPH) by using the direct-write, near-field electrospinning (NFES) technique and polyvinylidene fluoride (PVDF) micro/nano fibers (MNFs) as source materials. Here, we comprehensively show that transferred high performance transparent electrodes with Au-coated nanowire (NW) electrodes can be obtained using a facile and scalable combined fabrication route of both electrospinning and sputtering processes. Au-coated MNFs of a.c. 110 nm thick can significantly reduce junction resistance, which results in high transmittance (90%) at low sheet resistance (175 sq−1). The Au-coated MNFs electrodes also show great flexibility and stretchability, which easily surpass the brittleness of indium tin oxide (ITO) films. Further improvement in ATPH performance was realized by rolling the device into a cylindrical shape, resulting in an increase in power output due to the cooperatively enhanced effect. The rolled ATPH with 0.34 cm diameter produces a high output voltage of ∼4.1 V, current ∼295 nA at a strain of 0.5% and 5 hz. This can efficiently run commercially available electronic components in a self-powered mode without any external electrical supply. 其他題名： NANO 其他題名： Nanotechnology 出版者： England: IOP Publishing 出版日期： 2016-10-28 出處： Nanotechnology, 2016-10, Vol.27 (43), p.435403-435403 資源來源： Institute of Physics Journals 版權： 2016 IOP Publishing Ltd 識別號： ISSN: 0957-4484 識別號： EISSN: 1361-6528 識別號： DOI: 10.1088/0957-4484/27/43/435403 識別號： PMID: 27655248 識別號： CODEN: NNOTER
