“…Nowadays, flexible organic electronics hold a great potential in "next generation" applications, such as foldaway displays [1,2], wearable printable electronics [3][4][5], advanced biomedical sensors [3,6,7], communication technology [8,9], and virtual reality devices. Its unique combination of properties, such as flexibility, light weight, potential biodegradability, elasticity, and ductility with a possibility of production by means of cheap, solution-based techniques like spin-coating and printing, generated the tremendous attention of scientist and engineer communities [1][2][3][4][5][6][7][8][9][10].…”
