有鑒於消費性電子不斷地推陳出新，以及穿戴裝置的蓬勃發展，因著環保意識抬頭，電子廢棄物回收的不易彰顯了環保軟性電子元件的重要性。而非揮發式電阻式記憶體 (Resistive Random Access Memory, RRAM) 具有結構簡單、讀寫速度快、低功耗及CMOS相容等特點，被認為是次世代記憶體中，極具發展前景的元件。且有機材料之電阻式記憶體可製備於軟性基板上具可撓性，塗佈製程更適於大面積生產，低成本的製程相較於無機材料更具發展潛力。
故此篇論文選擇研究：一、吉利丁基板各項特性及其取代塑膠基板作為RRAM軟性電子元件的可行性；二、具生物分解性的基板應用於非揮發性電阻式記憶體，並以溶液式手法製備有機材料作為金屬-絕緣層-金屬之中的絕緣層薄膜。
首先研究不同來源之吉利丁基板的製作與其機械性質的探討，其表面粗糙度 (Rrms 2.42 nm)、透光性 (91%)、極限抗拉強度UTS (84.1 MPa) 、可彎曲性及生物可降解性等結構特性，有機會取代塑膠基板，進而提供未來以此基板作為軟性電子元件之基礎；最後為以生物纖維膜製作的非揮發性電阻式記憶體，模擬人體皮膚環境研究其電性。因生物纖維膜取自美容用面膜，其纖維交織緊密，具溶脹特性的優勢，製成電阻式記憶體後，整體元件厚度不到10微米，實現輕薄可貼膚之特性。另外設計了模擬人體皮膚具溫度、水分、油份及鹽分的環境量測，在此環境下，其開關比可達103，記憶保持力亦超過7400秒，且再放置兩個月後依然可多次讀寫，證實其具有不錯的電性表現，具極大潛力應用於醫用穿戴電子設備。

This thesis mainly applies biological substrates to non-volatile resistive memory and utilizes a solution method to prepare organic materials as the insulator film in the metal-insulator-metal structure.
Therefore, the thesis is divided into two parts. The first part is the discussion of the manufacture of the gelatin substrate and its mechanical properties, to be the basis of the application for flexible electronics. The surface roughness (Rrms 2.42 nm), transmittance (91%), ultimate tensile stress (UTS) (84.1 MPa), bendability, and biodegradability, these properties offer the gelatin film great advantage to compete with the PET plastic to be the substrate for soft electronics.
The second part is the discussion of the organic non-volatile resistive memory fabricated onto the bio-cellulose film. The bio-cellulose film is taken from a facial mask for beauty care, which is transparent and stretchable. The fabrication is utilizing the silver paste exploited to the bottom electrode, and the gelatin insulator layer was formed by a spin-coating process without a vacuum process and then the aluminum (Al) top electrode is deposited by DC sputtering. It can be observed that has the characteristic of bipolar switching behavior, that the current on/off ratio could be up to 4 orders.
Because of its tightly interwoven bio-fibers and excellent swelling characteristics, it was designed to simulate human skin with temperature, moisture, oil, and salt. In this environment, the components can still achieve good electrical performance. Showing that the current on/off ratio could reach 3 orders and the retention time could remain 7400 seconds.
