Abstract:	本論文利用近場電紡織技術(near-field electrospinning，NFES)，研究壓電奈米纖維並且製作成奈米發電機(nanogenetator，NG)/形變感測器，此技術在現今仍就是一項新穎的技術，此研究以直寫(Direct -write)方式將具有高度壓電性能的高分子材料聚偏氟乙烯(polyvinylidene fluoride，PVDF)利用近場電紡織技術與XY精密位移平台將奈微米纖維(nano /micro fibers，NMFs )精確的排列在可撓性基底上製作成壓電奈米發電機，並且進行一系列訊號量測與驗證。其一研究繼承實驗室之過往實驗，以印刷紙沉積壓電纖維，探討纖維性能並製成智能無電池式聲音感測元件(Intelligent and self-powered sound-sensing elements，ISSEs)，用以量測人體喉頭與音響所產生之動作與震動，而後我們結合了靜電發電機與壓電發電機做出綠能發電器，並採用具微米結構之塑膠片提高靜電與壓電效應輸出，成功讓混能式發電機有更高的輸出功率與適應性，並將其應用在收集再生能源上，與較常用之太陽能不同，此次收集風力能與水力(雨)能來轉換為電能，未來可望在穿戴式裝置與再生能發電裝置上有著很好的發展潛力。;In this paper, Near-field electrospinning (NFES) technology has studied and used to deposit the nano/micro fibers on the different base, then made into nano generator (NG) / deformation sensor, this technology is still a novel technology. In this study, polyvinylidene fluoride (PVDF), a polymer material with high piezoelectric properties, was deposited and accurately arranged on a flexible substrate by direct-write method using near-field electrospinning technology and XY precision motion stage as a piezoelectric nano-generator. Then use the sample to perform a series of signal measurements and verification. One of the research continued the past experiments in the laboratory, depositing piezoelectric nano/micro fibers on the printing paper to investigate fiber properties and came to an Intelligent and self-powered sound-sensing elements, (ISSEs), Used to measure the action and vibration produced by human throat and loudspeaker. In another study, experiment use the plastic film witch has an unique micro-structure to improve the electrostatic and piezoelectric effect output to increase the hybrid generator’s output power and adaptability, and its application in the collection of renewable energy combined the electrostatic generators and piezoelectric generators as a green energy collectors. The use of micro-structure of the plastic film improve the electrostatic and piezoelectric effect output, the success of the hybrid generator more high output power and adaptability, and its application in the collection of renewable energy. The collection of wind and water (rain) can be converted into electrical energy. Wearable devices and renewable energy collection devices has a very good development potential in the future.
