Mechanically gated electrical switches by creasing of patterned metal/elastomer bilayer films

Strain-gated logic devices are important for the development of advanced flexible electronics. Using a dual-monolayer-promoted film-transfer technique, flexible multilayer structures capable of undergoing large compressive deformation are prepared. Formation of a crease in the gap between electrodes at a geometrically tunable strain leads to the formation of an electrical connection in a reversible and reproducible fashion.
