Patent number: 9182618Abstract: A method of electrophoretic movement of liquid droplets/gas bubbles through a liquid crystal utilizes a direct (DC) or alternating (AC) electric field that is applied along the liquid crystal director (for liquid crystals with a positive dielectric anisotropy) or perpendicular to the director (for liquid crystals with a negative dielectric anisotropy). A perpendicular or tilted orientation of the liquid crystal molecules at the surface of the liquid droplet/gas bubble causes distortions, such that the fore-aft (or left-right) symmetry of the liquid droplet/gas bubble is broken. The asymmetric orientation of the liquid crystal around the liquid droplet/gas bubble allows both charged and neutral particles to be transported, even when the liquid droplets/gas bubbles themselves are perfectly symmetric (spherical).Type: GrantFiled: June 1, 2015Date of Patent: November 10, 2015Assignee: Kent State UniversityInventors: Oleg D.
