Electronic devices (10, 30, 50) utilizing electrically-controlled liquid components to accomplish device switching. Electric fields are used in a device structure to manipulate the position and/or geometrical shape of a conductive fluid or liquid (60, 24) using electrowetting. This manipulation regulates the flow of current between electrodes of the device structure, such as the source and drain regions (16, 20) of a transistor construction, by bridging a non-conductive channel (15) separating the electrodes (16, 20) so that the electrodes (16, 20) are electrically coupled.
