Develop graphene based highly sensitive touch and strain sensors connected with memristors and embedded in soft materials such as eco-flex. The graphene is chosen as its optical transparency will allow us to study the transmission of external stimuli through the soft material surrounding the sensors. This will help us to establish the role of skin mechanics through artificial means. The fabrication and electro-optic characterization of flexible electrodes and touch and strain sensors will be carried out. For memristors, the dry fabrication (i.e. free from conventional chemical processing) of graphene oxide (GO) will be carried out by plasma oxidation. For counter electrode graphene will be transfer printed on top of GO and a thin gold layer will be deposited at the edges of sample for electrical contacts. The graphene-based sensors will have planar capacitive structures. The sensors will be interfaced with compact electronics developed in other projects.
