Creation and use of graphene and 2D materials for device applications, with an emphasis towards scalability of the process towards the industry and compatibility with current or envisaged mass production techniques. I worked with a functionalised form of graphene, FeCl3-FLG and dubbed GraphExeter. Due to its improved properties, I have demonstrated that this material may outperfom other emerging transparent conductive electrodes. I worked embedding graphene with polymeric textile fibres to create wearable devices. Using my expertise in ACEL devices, I produced such devices on textile fibres using graphene electrodes. Also, I engineered such fibres to produce touch-sensors. I worked in a novel patterning and deposition method for solution-processed 2D materials. This process should be compatible with both roll-to-roll and CMOS processing. I demonstrated this creating flexible and transparent humidity sensors on PET, 1x1 cm2 Si chips and a whole 4'' SiO2/Si wafer.
