In 2005, we observed a novel phenomenon in soap films. In this phenomenon the soap film rotate under applying an electric field and an electric current. The direction and velocity of this rotation is completely controllable. Since 2005 we have focused on this problem. We show that this phenomenon is completely general, and can be observed in most of fluids and complex fluids. In this video we show that by using an alternating non-uniform electric field, we can produce flow in soap films. I think these works can be useful for manufacturing mixer in small scale, micro pump and controlling biological fluid flow in the body of a living creature. Hope presenting in your program help us to find new co-workers.
