Abstract: A method of making a combined sinter-ready silver film and carrier comprises the steps of: a) creating a carrier comprising designed openings; b) casting a silver film layer into the designed openings, for example casting a silver paste; and c) drying the carrier and silver film layer to form the combined sinter-ready silver film and carrier. The carrier may comprise a plastic carrier, which may be created by permanently bonding two plastic films, using a plasma bonding process or using a temperature stable glue. The carrier may comprise a stencil layer and a backing layer. The stencil layer may define the designed openings. The backing layer may be configured for sealing a bottom of the designed openings, wherein at the start of step b), a top of the designed openings may be open for receiving the cast silver film layer.

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.
