It consists in creating entire device arrays directly on the copper substrates used for the commercial production of graphene, after which complete and fully-functional devices can be transferred to a substrate of choice. This process has been demonstrated by producing a flexible and completely transparent graphene oxide-based humidity sensor. Not only does this device outperform currently-available commercial sensors, but it’s also cheap and easy to produce using common wafer-scale or roll-to-roll manufacturing techniques. ‘The conventional way of producing devices using graphene can be time-consuming, intricate and expensive and involves many process steps including graphene growth, film transfer, lithographic patterning and metal contact deposition,’ explains Prof David Wright from Exeter's Engineering department. ‘Our new approach is much simpler and has the very real potential to open up the use of cheap-to-produce graphene devices for a host of important applications from gas and bio-medical sensors to touch-screen displays.’ One of team’s main objectives was to increase the range of surfaces that graphene devices can be put on.
