+ - Diodes could drive swimming micro-robots

Submitted by finisterre
finisterre (666) 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."

If money can't buy happiness, I guess you'll just have to rent it.
