Journal ArticleDOI
Printable Nanocomposite Metalens for High-Contrast Near-Infrared Imaging
TL;DR: In this paper, a printable metalense composed of a silicon nanocomposite is developed to overcome the manufacturing limitations of conventional metalenses. The nanocompositionite is synthesized by dispersing silicon n...
Journal ArticleDOI
Broadband and pixelated camouflage in inflating chiral nematic liquid crystalline elastomers.
TL;DR: In this paper, pneumatically inflating thin membranes of main-chain chiral nematic liquid crystalline elastomers that have such properties are used to achieve color shifting from near-infrared to ultraviolet wavelengths with less than 20% equi-biaxial transverse strain.
Journal ArticleDOI
Transparent and flexible high power triboelectric nanogenerator with metallic nanowire-embedded tribonegative conducting polymer
TL;DR: In this article, the authors developed a novel concept of a highly efficient, transparent, and flexible triboelectric nanogenerator (TF-TENG) based on a metallic nanowire-embedded conducting polymer as a contact electrode.
Journal ArticleDOI
Physical mechanism for flat-to-lenticular lens conversion in homogeneous liquid crystal cell with periodically undulated electrode
TL;DR: The LC device having an index-matched planarization layer on the undulated electrode is capable of achieving the electrical tunability from the flat surface to the lenticular lens suitable for 2D/3D convertible displays.
Journal ArticleDOI
Design and fabrication of liquid crystal-based lenses
TL;DR: In this paper, the underlying mechanisms for the focusing effect and the tuning capability inherent to the lens configuration are described, along with recent progress on the LC-based lenses for reconfigurable optical processing and autostereoscopic displays.
