本研究設計ㄧ新穎的多紡口電紡結構，搭配近場靜電紡絲製程技術(Near-field Electrospinning)，達到同時電紡多根PVDF纖維的目標，再導入玻璃滾筒式收集方式，製作出批量綑狀且高機能的聚偏氟乙烯(Polyvinylidene fluoride, PVDF)壓電纖維。製程中，藉由定量注射幫浦的輔助，使PVDF溶液裝填於以印刷電路板(Printed circuit board, PCB)與錫球結構製作的多紡口系統結構中，施予1.0*107至1.6*107V/m的環境電場，使PVDF液滴而形成泰勒錐狀(Taylor cone)，其突破表面張力形成極細的PVDF壓電纖維，並批量收集於滾動中的玻璃滾筒。從玻璃滾筒取下的PVDF壓電纖維，藉由掃描式電子顯微鏡(Scanning electron microscope, SEM)與微型拉伸強度測試(Microforce tensile testing)量測出本PVDF壓電纖維具有1.5-4.5μm線徑及1.21GPa的楊氏模數，且經由X光繞射分析儀(X-ray diffraction, XRD)驗證，此PVDF壓電纖維，有較高於PVDF粉末之β相壓電結晶結構強度(2θ=20.5度)。最後，將PVDF壓電纖維兩端固定於可撓性基板的銅電極上，形成壓電特性量測裝置，其發現當結構上的壓電纖維受到2~7 Hz的振盪頻率時可以得到18 mV至76 mV電壓訊號及0.42 nA至1.1 nA的電流訊號，由此可證本研究的PVDF壓電纖維可於低頻環境中獲取微型能量，在未來可經由編織的方式，使此纖維形成ㄧ高機能布料，應用於自發性獵能衣物。

In this study, we improve the near-field electrospining by multi-nozzle spinnerets with a glass cylindrical collector in order to produce multi-fibers at a time and fabricate mass and cluster-shape and functional permanent piezoelectricity of PVDF (Polyvinylidene fluoride) fiber arrays. Throughout the process, the PVDF macromolecular solution was filled in multi-nozzle spinnerets structure composed of the designed Printed circuit board and Solder ball structures. With quantitative injector and high electric field : 1*107-1.6*107V/m, PVDF drops can be observed to form Taylor cones and overcame surface tension of the solution itself, then extra-fine PVDF fibers were obtained on the glass cylindrical collector.From measurement of scanning electron microscope and microforce tensile testing , the result reveals that the diameter of the electrospun nanofibers is 1.5-4.5um and the Young’s modulus is 1.21GPa. From the observation of XRD (X-ray diffraction), it shows a high diffraction peak at 2θ=20.5° of piezoelectric crystal β-phase structure. For the electricity measurement system, PVDF fibers were firmly bonded to the copper foil electrode pair. Under 2-7 Hz vibration, the piezoelectric fibers harvesting device with parallel electrode could generate the voltage of 18-76 mV and the current of 0.42 - 1.1 nA , respectively. These good piezoelectric PVDF fibers with excellent mechanical and electrical energy conversion are able to generate energy from low-frequency vibration of environment, so these high performance fibers can be applied to spontaneous hunting clothes in the future.
