Latest Invention: Air-Conditioned Bulletproof Vests


A team of scientists from the Swiss Federal Laboratories for Materials Science and Technology (Empa) recently came up with the world's first air-conditioned bulletproof jacket based on a special technology called Coolpad that helps police stay cool in hot days.

It is worth mentioning that the Coolpad technology elaborated by Empa was initially developed for cooling clothes for different medical applications.

Researchers say that the built-in Coolpads evaporate sweat through the material, thus helping the wearer to stay cool.

Besides, the bulletproof jacket has a tiny fan that easily fits into the garment and blows air inside the vest to offer more cooling. To be able to incorporate the fan, researchers at Empa teamed up with Eschler, a textile company from Switzerland, to develop a special fabric spacer that is both stable and flexible.

In order to quickly refill the cool pads with water, scientists created a portable filling station the wearer can easily attach to the jacket using a quick-release fastener.

Fully-charged batteries allow the vest to work in hot conditions for 3 to 4 hours. Empa mentioned that the first bulletproof vests will be manufactured by project partner Unico Swiss Tex GmbH.
