Ballistic armor

"Ballistic armor is manufactured from electrically sensitive polymer sheets that intrinsically react to the violent impact of a bullet or an explosion by 'stiffening' in response and absorbing the majority of the damage. These polymer sheets must be charged before use; after the charge has dissipated they lose their reflexive properties and should be discarded."
