DESCRIPTION:Flexible electronics is an ever-expanding research area. Appli
 cations include touch screens\, electronic paper\, sensors\, photovoltaic 
 cells and electronic textiles. Printing is the most promising technique fo
 r cheap large-area flexible electronics and is now well-established to man
 ufacture thin-film transistors (TFTs) based on organic semiconducting inks
 . For instance\, in displays\, TFTs are currently made of poly-silicon or\
 , more recently\, of Indium Gallium Zinc Oxide (IGZO). However\, IGZO is e
 xpensive\, due to Indium scarcity and both poly-silicon and IGZO are neith
 er printable nor fully-flexible (i.e. flexible in three dimensions). On th
 e other hand\, the electron mobility of semiconducting inks is still much 
 lower than standard poly-silicon technology\, making the actual printable 
 electronics prototypes extremely slow.\n\nAfter the isolation of Graphene 
 in Manchester in 2004 and the 2010 Nobel Prize in Physics to Andre Geim an
 d Kostya Novoselov\, graphene came at the centre of an ever expanding rese
 arch area. Near-ballistic transport and high mobility make it an ideal mat
 erial for nanoelectronics\, especially for high frequency applications. Fu
 rthermore\, its optical and mechanical properties are ideal for thin-film 
 transistors and transparent and conductive electrodes. Here I will show ho
 w the extraordinary properties of graphene can be used to fabricate graphe
 ne-based printable\, transparent and conductive electrodes and TFTs for fl
 exible electronics.
