Liquid Crystals: Cholesteric Liquid Crystal Shells as Enabling Material for Information‐Rich Design and Architecture (Adv. Mater. 30/2018)

Abstract

Cholesteric liquid crystal shells provide omnidirectional reflection with selectivity in wavelength and polarization. By tuning the reflection wavelength from the infrared to the ultraviolet, via the visible, numerous applications can be envisaged, as summarized by Mathew Schwartz, Gabriele Lenzini, Jan P. F. Lagerwall, and co-workers in article number 1707382. These applications range from tokens for secure authentication to information-rich signage for humans and/or robots, including autonomous vehicles.
