The electric field actively controls and regulates heat transfer according to either a first mode by reorienting the director of the liquid crystal material and therefore switching the thermal conductivity, or by a second mode electrically inducing convection current flow cells for increasing heat transfer between the elements by a factor as great as 10 or more.Other References
