We present an inexpensive, repeatable, and efficient method of patterning silver nanowires onto polydimethylsiloxane (PDMS) using a mould based approach. A micro-milling machine is used to prepare an aluminum mould with a raised pattern, so that PDMS cured in these moulds is imprinted with the design. A solution of silver nanowires and ethanol can than be injected into the pattern. This method can be used to pattern silver nanowires onto PDMS in any 2D layout, meaning it can be extended to produce a wide range of PDMS/silver nanowire-based sensors and devices. We demonstrate this by the development of two separate patterns. An intricate logo is developed in order to demonstrate the capability of patterning curved and sharp edges, and a strain gauge is developed in order to demonstrate a functional device.
