Innovative research led by Professor Daping Chu has produced a liquid crystal-based dielectric metasurface, reducing manufacturing complexities and improving optical device performance, with significant implications for future liquid crystal technologies. Credit: SciTechDaily.com
In this study, Professor Daping Chu’s team at the University of Cambridge developed a novel liquid crystal-based tunable dielectric metasurface. By leveraging the dielectric metasurface’s inherent alignment effect on liquid crystals on top of its electrically controllable properties, the need for liquid crystal alignment layer materials and related processes is eliminated, thus saving device manufacturing time and costs.
At the same time, the research team also achieved a modulation depth of 94% in the near-infrared communication wavelength band during experiments.

Researchers Develop Programmable Meta-Fluid with Tunable PropertiesResearchers have created a meta-fluid that can be programmed to have various properties such as springiness, optical properties, viscosity, and the ability to transition between Newtonian and non-Newtonian fluid. The meta-fluid uses small elastomer spheres that change the characteristics of the fluid when pressure is applied. This development has potential applications in robotics, shock absorbers, and optical devices.

Scientists develop tunable colored films for displays and sensorsResearchers at the Indian Institute of Science (IISc) have developed flexible films that exhibit bright colors purely by virtue of their physical structure, without the need for any pigment. When stretched, the films exhibit a change in color as a response to the mechanical deformation.
