碩士 === 國立成功大學 === 系統及船舶機電工程學系 === 104 === In this paper, we fabricating flexible electronic circuits on paper and combine PVDF(Polyvinylidene fluoride) piezoelectric fiber using NFES(Near-field Electrospinning) to develop the flexible piezoelectric sensing element. We uncommonly adopt screen-printing technology to produce the electrodes, and design its d33 mode patterns. The experimental results show that the type of electrode is key to enhance the output voltage. The parallel type can induce an average of 159.2 mV positive voltage under the tapping experiment. Compared to the normal series type has a 3.7 times upgrade And five pairs of the series type for the best design of the electrode pattern, the output voltage as high as 431.8 mV. however, paper can be folded and creased (repeatedly), shaped to form threedimensional structures, trimmed using scissors and disposed of by incineration. Paper-based electronic circuits are thin and lightweight ; they should be useful for applications in consumer electronics , for disposable systems in wearable sensors. Finally, we design the prototype of the Self-powered Paper Keyboard and evaluate its feasibility.
