Abstract

TThe future of electronics lies in flexible devices that are stretchable, bendable, foldable, transparent, and wearable. Sooner, currently used rigid devices will be substituted by the light-weight, convenient, and durable flexible circuits, displays and storage devices. Currently, most of the touch panels and display devices use indium tin oxide (ITO), which is transparent and conductive but have poor mechanical and chemical stability with high fabrication cost. Contrarily, flexible electronics is a new approach where electronic circuits are assembled on flexible substrates such as metal nanowires, graphene, carbon nanotubes, and conducting polymers. Along with the flexibility and stretch ability, the simultaneous excellence in mechanical and electrical performance is also desired. Mostly used conventional inorganic-based materials exhibit poor mechanical properties limiting their potential incorporation in flexible devices.
