USA Successfully Develops Solar Bulletproof Vest

Recently, scientists in the United States have developed a new technology solar energy. Bulletproof vests The bullet proof ability is comparable to that of ordinary bulletproof vest, and uses solar energy to bullet proof and soft tissue. This is the latest achievement in the application of nanotechnology.

It is understood that this Bulletproof vests It is made of new materials. This material is soft and thin, and it is light and thin. be flexible 。 It is made of nanowires, such as germanium and silicon, which are woven into traditional fabrics or surrounded by some hard plastic products, so that they have the same bullet proof function as Kevlar and can use solar energy and other more functions.

According to Brian Korgel, the inventor of this new type of bulletproof vest, the paper used by people is usually pressed by wood fiber. The thin paper material of the bulletproof vest is compacted by a large number of nanowires converted from semiconductor components such as germanium and silicon, and so on. The Blaine paper is made up of a new type of bulletproof vest.

Germanium is known to be brittle and hard. In fact, the "thin paper" material made of germanium is very strong in plasticity, bending at will without fear of damage. In particular, the individual germanium nanowires have an unexpected degree of seed setting, and even have a similar strength and weight ratio to Kevlar. Usually, the impact force of germanium can not be affected by germanium nanowires. However, the use of germanium nanowires to make bulletproof vests is not enough, because Kevlar is not only bulletproof because of its good bulletproof performance, but also because of the strong ballistic performance of the whole fiber, germanium nanowires are slightly inferior to Kevlar. So Blaine and his colleagues began planning to develop another use, solar energy, with the use of semiconductor components in new fibers.

In general, germanium absorbs light that some human eyes can see and absorbs invisible infrared rays. However, since the photovoltaic effect of germanium is far less than that of silicon, the scientists also developed a silicon nanowire similar to thin paper. It is understood that silicon nanowires can convert more sunlight into electricity, and individual silicon nanowires are 35% stronger than germanium nanowires, and are more resistant to corrosion. In this way, the germanium silicon nanowire fabric inside the bulletproof vest and the silicon germanium nanowires around the hard plastic will transform the solar energy into electricity, which will drive the sensors inside the bulletproof vest and some other electrical equipment to play a better bulletproof role.
