ABSTRACT:
A switchable element is described, which comprises a fluid chamber (111) containing a polar (101) and a non-polar (102) liquid, which are immiscible. The element is further provided with two electrodes (103,104), which are arranged to control the spatial distribution of the liquids, by means of an applied voltage across two the two electrodes. By the addition of surfactant to one or both of the liquids, the actuation voltage of the element is lowered. The element can work for example as an optical device or a motor.
