Diodes used for propulsion
13:59 in Hardware, News by fini
“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.”
