A new gel, called d30, hardens immediately on impact and the military hopes to use it on their helmets to help dissipate the kinetic energy from bullets and shrapnel.

The d3O gel has already expanded into a range of sporting goods and is found in ski gloves, shin guards, ballet shoe pointes and horse-riding equipment. The substance relies on “intelligent molecules” that “shock lock” together to absorb energy and create a solid pad. Once the pressure has gone they return to their normal flexible state.

The gel is stitched into clothing or equipment that is supple until it stiffens into a protective barrier on impact.

If the product is taken on by defence contractors it could be used to reduce the current bulky and restrictive armour used by troops in on the frontline with gel pads inserted into key protective areas.

Most military personnel aren’t dying from head wounds.  It’s the flying shrapnel.  The military is investing £100,000, which means that they don’t fully support the idea yet or they plan to only use it with special forces.

More information on costs is needed, as well as how well the gel works, before a final decision can truly be made.
