  7. Abstract:
  8. Graphene is a single-atomic two-dimensional crystal that has considerable properties due to its unique structure and physics with applications in different fields. Due to its atomic thin thickness, substrates have a considerable effect on the electrical properties of Graphene. As these effects are determinative of the general behavior of systems, one should consider this effect in the design and fabrication of a device. Moreover, the conventional fabrication methods for Graphene-based electronic devices restrict the possibility of the device fabrication on a wide range of substrates, specially flexible and biocompatible substrates.In this work, the LPCVD Graphene growth process has been optimized to grow high quality few layer Graphene on the copper foil surface. In addition, a novel fabrication process has been proposed with which Graphene-based devices can be fabricated on flexible and biocompatible substrates. Afterward, the I-V curves of the transferred Graphene on different biocompaticle substrates have been measured and the sheet resistance of Graphene on different substrates are achieved. Additionally, a large area Graphene heater is fabricated on the biocompatible substrates to be used for bioelectronics and biochemistry applications
