Abstract: This invention discloses formulations of mutually compatible sets of graphene, graphene-carbon, metal and dielectric inks for the fabrication of high performance membrane touch switches (MTS). The compositions of these inks are optimized to achieve higher degree of compatibility with highly engineered polymeric substrates, thereby offering a holistic solution for fabricating high-performance MTS. These sets of materials can also be used for fabrication of sensors, biosensors and RFIDs on flexible substrates, such as polymers and papers.
