The diving suit is upgraded in weight and can be used for hours at 10 ° C under water.

With the development of society, human beings have increasingly demanded the quality of their own life, and diving has become a very popular sport. The successful commercial use of various underwater underwater breathing equipment has attracted a large number of diving enthusiasts.

Normally, the flow of seawater can carry away the body's heat, and the rate at which seawater carries away body temperature is 25 times that of air. After all, human beings do not live in the ocean. In low-temperature seawater, the human body can easily lose temperature. Therefore, humans need various equipment, such as oxygen cylinders, diving suits, etc. to dive, water temperature, water speed and other conditions have a greater impact on diving. Divers will wear different protective clothing according to the water temperature. The most common one is the neoprene insulation suit. It protects the water in the water between 10 ° C and 25 ° C by blocking the cold water from the outside through the tiny air cavity in the foam rubber. .

Whales, seals, and other marine mammals are well adapted to the cold waters of the Arctic, because they have a thick layer of fat beneath their skin. Inspired by this, the US Navy has developed a “artificial fat” that is used in wetsuits to allow divers to work for hours in cold underwater environments.

The project was funded by the US Naval Research Office (ONR), MIT and George Mason University, and Michael Strano and Jacopo Buongiorno. The research team added a heavy inert gas such as helium and neon to the neoprene foam to achieve a concentrated fat effect. According to the ONR laboratory test, the upgraded diving kit can work effectively for several hours at 10 °C instead of the previous few minutes. The successful research of the project has brought good news to underwater workers and scuba divers.
