我們提出一個在未來很有前景的方法，利用低成本來大量製成石墨烯，在本論文中我們主要在探討以微波輔助法製成石墨烯於可饒性基板PDMS傳感器之研究，實驗共分三部分，第一部分，以不同參數的溶劑插層後使用微波輔助還原法來製備出石墨烯。第二部分，並以拉曼光譜(Raman)進行分析I2D/IG訊號比來判定石墨烯品質，經過一系列的測試我們發現在硫酸:硝酸鈉:去離子水比為35毫升:0.7毫克:5毫升有最佳的條件，I2D/IG訊號比為0.63。第三部分，藉由拉伸測試來量測應變傳感器進一步得到應變係數(gauge factor)，此係數可代表傳感器的靈敏度且應變量(strain)可達到30%，另外我們做了彎曲感測，使石墨烯在未來有更多更廣的應用可能性。傳感器基板我們選擇了聚二甲基矽氧烷(Polydimethylsiloxane,PDMS)，此材料具有疏水性、無毒、有彈性、透光性佳等，讓未來石墨烯應變傳感器的應用端可以往生醫，作為人體的感測器。

In this study, we use a low cost prodecure to make a large amount of graphene. we mainly discuss the microwave-assisted method for the production of graphene on a PDMS sensor. The experiment is divided into third parts. In the first part, the microwave-assisted reduction method was used to prepare graphene after solvent intercalation with different parameters. In the second part, the I2D/IG signal ratio was analyzed by Raman spectroscopy to determine the quality of graphene. After a series of tests, we found that the ratio of sulfuric acid : sodium nitrate : deionized water was 35 ml : 0.7 mg : 5 ml. In the third part, By straining test, we can get the gauge factor. The coefficient can represent the sensitivity of the sensor and the strain can reach 30%. In addition, we have performed bending sensing to make Graphene has more and more application in the future. We chose Polydimethylsiloxane (PDMS) as a sensor’s substract. This material is hydrophobic, non-toxic, elastic, and high transmission. The application of the sensor can be used in the human body.
