“Finally, now I can swim in shark-infested waters like I’ve always wanted. A bright fellow called Vladimir Vlad has filed a patent for a shark-repellent wet suit that creates an electrical field. The idea is that sharks have sensitive receptors in their noses which would normally help them track prey, but when faced with an especially strong electrical field, they will back off. This wet suit would be made of metal and neoprene, with thin piezoelectric ceramic fibres woven in. Voltage is then delivered by the fibres depending on their length. The suit continually generates several volts which flow through the water, and the faster you swim, the higher the voltage…” (Gizmodo)
