軟性電子在近年中廣泛的被應用於軟性有機發光二極體(OLED)顯示器、觸控面板、穿戴式生理監測裝置等消費性電子產品之中，以往的電子元件基材大都以玻璃或是硬塑膠為主，但受限於其易碎不可撓曲，無法滿足未來軟性電子產品的應用需求。軟性電子講求低成本與大量製造，因為銀奈米線可配合濕式製程與卷對卷(Roll to roll)製程整合，進行大面積連續的製造以降低成本，且銀奈米線擁有優秀的導電度，相較於傳統銀奈米顆粒電極，其高長度與直徑比的結構提供良好的機械性質，銀奈米線排列性可降低接觸電阻進一步提升導電性，因此本研究重點於實現排列銀奈米線微電極製程，並應用於觸覺感測電子皮。
　　本研究提出以快速滾印製程下，透過以氧電漿處理金屬遮罩之矽膠膜，於矽膠表面形成局部圖案之親水性，滾印於矽膠膜產生的塗墨溶液液膜破裂使銀奈米線往表面張力大的區域沉積，得到圖案化的銀奈米線電極，銀奈米線溶液受到拖曳形成液膜的過程中，排列銀奈米線的流體動力幫助了銀奈米線朝著滾印方向排列。本研究滾印銀奈米線微電極所能達到最小電極線寬為50 μm，並在此情況下展現出6.3 Ω/□的片電阻值，且雙層垂直滾印下更能達到3.1 Ω/□；除此之外，銀奈米線微電極擁有良好撓曲與拉伸抗性，在撓曲半徑2.5 mm下彎曲1500次電阻值僅提升119%；而雙層垂直滾印銀奈米線電極在拉伸應變在達到60%仍保持導電性，相較於單層滾印之銀奈米現只能承受20%的拉伸應變，本研究驗證了雙層垂直相交銀奈米線網絡大幅地提升了拉伸的強度。
　　最後以創新的滾印銀奈米線微電極，製作了8 × 8的觸覺感測陣列電極，每一個感測點以PDMS為中間層之三明治結構的平行板電容，其壓力感測範圍介於73.5 – 514.5 Pa，靈敏度為0.54 kPa-1。

Flexible electronics have been widely used in consuming electronic products such as wearable health monitoring devices, flexible OLED displays and touch panel in recent years. Most of the conventional electronic component substrates are glass or rigid plastic. Glass and rigid plastic substrates are hard and stable, but restricted by its brittleness and inflexibility. Fabrication of flexible electronics emphasizes low cost and mass production. However, Roll-printed silver nanowires (AgNWs) process can be integrated into roll-to-roll processes to enable high volume and continuous manufacturing with low cost. AgNWs have attracted significant interest for conductive electrodes. Not only its high conductivity but also excellent mechanical compliancy due to the large length-to-diameter aspect ratio structure. In order to solve the junction resistance between AgNWs and surface roughness. Alignment of AgNWs is proposed to improve the problems. This research focuses on development of the highly aligned AgNWs microelectrode by roll-printing, then applied to the tactile sensing electronic skin.
　　In this study, I developed the fabrication of pattering AgNWs microelectrode by roll-printing process. Through the oxygen plasma treatment on the silicone rubber which is covered with a metal mask. The surface of silicone rubber formed different surface tension. In the one-step roll-printing assembly, the liquid film rupture during to the solvent evaporation. Then the ruptured liquid is driven to the region with higher surface tension and form AgNWs microelectrode. Besides, the interaction between shear-induced hydrodynamic enables the alignment of AgNWs in the direction of drag. In the results, the roll-printed AgNWs microelectrode achieve a minimum line width of 50 μm, and exhibits a low sheet resistance of 6.3 Ω/□ in this case. The double-layer cross-printed AgNWs microelectrodes displayed lower sheet resistance 3.1 Ω/□. In addition, the roll-printed AgNWs microelectrode show the remarkable bending and tensile strength. The resistance is only increased by 119% during 1500 cycle of bending at bending radius 7.5 mm. The double-layer cross-printed AgNWs microelectrode keeps the conduction when uniaxial tensile strain up to 60%. In comparison, the single-layer can withstand only 20% tensile strain. This study demonstrated the tensile strength significantly increasing because of perpendicularly intersecting AgNWs network.
　　Eventually, an 8 × 8 tactile sensing array was fabricated by an innovative AgNWs microelectrode. Two patterned AgNWs electrodes sandwiched a PDMS layer for a parallel plate capacitor. The pressure sensing range is between 73.5 – 514.5 Pa with the sensitivity 0.54 kPa-1.
