Jang Ung Park,Matthew T. Hardy,Seong Jun Kang,Seong Jun Kang,Kira Barton,Kurt Adair,Deepkishore Mukhopadhyay,Chang Young Lee,Michael S. Strano,Andrew G. Alleyne,John G. Georgiadis,Placid M. Ferreira,John A. Rogers +12 more
TL;DR: Key aspects of the physics of this approach, which has some features in common with related but comparatively low-resolution techniques for graphic arts, are revealed through direct high-speed imaging of the droplet formation processes.
Journal ArticleDOI
Printed assemblies of inorganic light-emitting diodes for deformable and semitransparent displays.
Sang Il Park,Yujie Xiong,Rak-Hwan Kim,Paulius Elvikis,Matthew Meitl,Dae-Hyeong Kim,Jian Wu,Jongseung Yoon,Chang-Jae Yu,Zhuangjian Liu,Yonggang Huang,Keh-Chih Hwang,Placid M. Ferreira,Xiuling Li,Kent D. Choquette,John A. Rogers +15 more
TL;DR: Methods to fabricate and assemble inorganic light-emitting diodes provide a route toward transparent, flexible, or stretchable display devices and for assembling and interconnecting them into unusual display and lighting systems.
Journal ArticleDOI
Ultrathin silicon solar microcells for semitransparent, mechanically flexible and microconcentrator module designs
Jongseung Yoon,Alfred J. Baca,Sang Il Park,Paulius Elvikis,Joseph B. Geddes,Lanfang Li,Rak-Hwan Kim,Jianliang Xiao,Shuodao Wang,Tae-Ho Kim,Michael J. Motala,Bok Yeop Ahn,Eric B. Duoss,Jennifer A. Lewis,Ralph G. Nuzzo,Placid M. Ferreira,Yonggang Huang,Angus Rockett,John A. Rogers +18 more
TL;DR: Modules that use large-scale arrays of silicon solar microcells created from bulk wafers and integrated in diverse spatial layouts on foreign substrates by transfer printing are described, including high degrees of mechanical flexibility, user-definable transparency and ultrathin-form-factor microconcentrator designs.
Journal ArticleDOI
Microstructured elastomeric surfaces with reversible adhesion and examples of their use in deterministic assembly by transfer printing
Seok Kim,Jian Wu,Andrew Carlson,Sung Hun Jin,Anton Kovalsky,Paul Glass,Zhuangjian Liu,Numair Ahmed,Steven L. Elgan,Weiqiu Chen,Placid M. Ferreira,Metin Sitti,Yonggang Huang,John A. Rogers +13 more
TL;DR: Experimental and theoretical studies of pressure modulated adhesion between flat, stiff objects and elastomeric surfaces with sharp features of surface relief in optimized geometries show the strength of nonspecific adhesion can be switched by more than three orders of magnitude.
Journal ArticleDOI
Mechanisms, Capabilities, and Applications of High-Resolution Electrohydrodynamic Jet Printing.
TL;DR: This review gives an overview of techniques used for high-resolution jet printing that rely on electrohydrodynamically induced flows to provide unique opportunities not only in scientific studies but also in a range of applications that includes printed electronics, tissue engineering, and photonic and plasmonic devices.
