Unlike liquid, this liquid refers to an alloy, which has the advantages of more wear resistance, lighter weight and higher strength. Mechanical exoskeleton (mechanical exoskeleton), or Powered exoskeleton, is a kind of mechanical device which is made of steel frame and can be put on by people. This kind of equipment can provide extra energy for limb movement. At present, there is no safe energy source to provide the corresponding power for the exoskeleton. Moreover, the exoskeleton is still defective, and people still need to be stressed, which is unbearable beyond compliance. Unless it is as comprehensive as Iron Man, it is difficult to achieve it.

Definition of liquid metal: liquid metal refers to an amorphous metal, which can be regarded as a mixture of positive ion fluid and free electron gas. Some metals, such as mercury, are liquid at room temperature because of their low melting point.

This great discovery may make our power suit more perfect, and it will also have a great impact on China's military cause. We have all seen Iron Man and know that his costume is very strong. If we design that set of power suit, can we leap into the ranks of world powers? The answer is obvious.

The key difference between endoskeleton and exoskeleton is protection. I think this liquid metal exoskeleton will also become a dazzling star in China's medical career, because it seems to help people to carry out life activities more conveniently. Although there is still a little distance from us now, we must overcome difficulties and go forward bravely, right?

Militarily, the exoskeleton will help the soldier to fight better, because he can get better protection, carry more weapons and equipment and have stronger physical fitness than normal people. In medicine, exoskeleton can serve us well because it can make us more convenient, and as a normal person, these influences are great.
