Abstract
A fluid structure control device has a liquid chamber holding a solution containing an electrolyte dissolved therein and conductive particles dispersed in the solution, and a pair of electrodes for applying an AC voltage to the conductive particles in the liquid chamber. Electro-osmotic flows are caused to occur due to electric double layers induced at the interface between the solution and the conductive particles by application of a voltage, thereby producing interaction among the conductive particles to displace the conductive particles and change reversibly the dispersion state of the conductive particles in accordance with the applied voltage.
