Submission + - Diodes could drive swimming micro-robots

finisterre writes: Diodes can be made to 'swim' through salt water by hitting them with an alternating electric field. The applied field induces a current that sets up a field between the diode's electrical contacts and creates a propulsive force. The abstract of the paper in Nature Materials is freely available. New Scientist has videos of the swimming diodes in action.

Line Printer paper is strongest at the perforations.
