Holographic metasurface gas sensors for instantaneous visual alarms.
Inki Kim,Won-Sik Kim,Kwan Kim,Muhammad Afnan Ansari,Muhammad Qasim Mehmood,Trevon Badloe,Yeseul Kim,Junho Gwak,Heon Lee,Young-Ki Kim,Junsuk Rho +10 more
TL;DR: In this article, a compact sensor platform that integrates liquid crystals and holographic metasurfaces is proposed to autonomously sense the existence of a volatile gas and provide an immediate visual holographic alarm.
Journal ArticleDOI
Stimuli-Responsive Dynamic Metaholographic Displays with Designer Liquid Crystal Modulators.
Inki Kim,Muhammad Afnan Ansari,Muhammad Qasim Mehmood,Won-Sik Kim,Jaehyuck Jang,Muhammad Zubair,Young-Ki Kim,Junsuk Rho +7 more
TL;DR: Liquid crystals (LCs)-integrated metaholograms for ultracompact dynamic holographic displays are proposed, which will provide a path to external stimuli-driven "smart" sensing and display applications such as hologram labels for temperature/pressure/touch monitoring and interactive holographic shows with haptic motion recognition.
