British researchers have invented a kind of external shock by rapid solidification after the jelly, which can effectively absorb the kinetic energy. British media reported that the British planned to use this gel to enhance helmet ballistic performance.
"Daily Telegraph" reported on February 27, this gel called "d3O", can be placed in the soldiers inside the helmet, can weaken the momentum bullets or shrapnel half, and then prevent them from penetrating  bulletproof helmets.
British Ministry of Defense has awarded the invention of this gel £ 100,000 enterprises (about 140,000 U.S. dollars) reward.
Inventor Richard Palmer said, still or slow-moving state, this gel the separation between molecules, while "in the event of high-speed impact, molecular intertwined and locked together to become strong." External force disappears, automatically restore soft gel.
He said that this jelly has been used to make ski gloves now, ballet shoes, wrist and other sports.
"Daily Telegraph" said that if the field can be used in national defense, this "smart" hydrogel can replace heavy armor, military equipment, a few lightweight gel pad can effectively bulletproof life-saving protection.
