Nanowerk  June 3, 2022 Researchers in Japan have developed a liquid whose dielectric permittivity can range from 200 to 18,000 in just half a minute when light is shone on it. They combined two molecules – a liquid crystal that has two phases, one with a low and one with extremely high dielectric permittivity. The second molecule is light sensitive. When blue light was shined on the combined molecule, it switched from the low-dielectric-permittivity phase to the high one; when green light was shined on the fluid it reversed the situation, causing it to return to the low-dielectric-permittivity phase. They […]
