In the movie "The Meg", the scene of sharks eating people is terribly frightened. In reality, every year, there are still terrible news about shark attacks on tourists in bathing beaches all over the world. On the territory of the overlord in the sea, do humans have the ability to defend themselves?
Now a new diving suit can make sharks avoid humans. This suit takes advantage of a characteristic of sharks. There is a very sensitive receiver in the shark's nose, which can detect the electric field in the water. This helps them track their prey. But if the electric field is too strong, they will turn around and slip away.
In addition to using metal and neoprene as common diving suits, a small amount of piezoelectric ceramic fiber is added to the new diving suit. The diving suit covers the trunk and limbs. When moving, the piezoelectric material will deform and generate electric charge, which is collected by the electrodes on the diving suit.
