Invented by Vladimir Vlad, the electric field shark repellent wet suit is, er, outfitted with piezoelectric ceramic fibres. As the wearer moves through the water, it generates several volts that will freak out any nearby sharks. From New Scientist:
If the diver sees an undeterred shark and swims fast to get away – a natural reaction, one suspects – the suit generates much higher voltages and stronger fields.
If the shark still fails to get the message and bites the suit, it gets a shock in the mouth and – hopefully – gives up for the day.
