When an electronic conductor was placed in a fluid filled channel with an appropriate external electric field,Faradaic reactions could take place at both ends of the conductor,which was called a bipolar electrode.[1]We report that conducting objects could be propelled in folded liquid filled channels by bipolar *** approach was based on controlling the formation of hydrogen bubbles at one extremity of a bipolar *** this work,copper wires used as microswommers could move in folded channels with angles from 30° to 180° by bubble propulsion and the velocity fluctuated over time.A proportional relation between polarization voltage and average velocity in linear channel was *** motion of microswimmers could be controlled within these types of channels in space and time,which might broaden the applications of micromachines in bipolar electrochemistry.
