Such pointy-like things often require huge energy in the course of voyage, which requires that the ship has an optimal streamline shape to reduce voyage resistance as much as possible, but some marine organisms such as barnacles, oysters and the like often adhere to the ship to bring huge resistance to voyage of the ship, and even can increase the energy consumption of the ship by more than 5%, bringing huge economic loss.
The existing common biofouling prevention method utilizes toxic chemical coating or heavy metal coating to inhibit adhesion of marine biofouling organisms such as barnacles, oysters and the like, but the method also has influence on health of other marine animals. The other mode is to manually remove marine fouling organisms adhered to the bottom of the ship through tools such as a shovel, but the mode needs manpower to remove the marine fouling organisms slightly, and is time-consuming and labor-consuming, and the bottom of the ship can be damaged. In nature, the living things such as mosquitoes, ticks and the like can pierce the skin of the human body with little effort through a rapid vibration mode, which deserves reference.
