23_11/2013Microcontact Printing: Ultrathin Sticker-Type ZnO Thin Film Transistors Formed by Transfer Printing via Topological Confinement of Water-Soluble Sacrificial Polymer in Dimple Structure (Adv. Funct. Mater. 11/2013)

Sticker-type electronics give electronic functions to unconventional substrates. On page 1375 Heung Cho Ko and co-workers demonstrate an advanced methodology to guarantee both stability in device fabrication and high-efficiency transfer printing of final devices to enable such a stick-and-play system. They employ a water-soluble sacrificial layer on a dimpled handling substrate, which enables the topological confinement of the ultrathin substrate.
