Stab vest ideas


A layer of conductive fibres beneath a few layers of insulating material, acting as a switch - if the fibres in one direction (say, horizontal) are broken, the circuit switches on, and the unbroken fibres in the opposite direction (vertical) conduct the charge from the capacitor through the knife and the attacker, down to the ground.

Active Material

A series of pockets interwound with tensile strands, such that when a fibre is severed, it contracts at high speed and somehow deflects the path of the blade to the side. With enough layers like this it could create a shear force that deflects the attack and pushes the victim sideward in the same action. The key is the energy stored in the material, which is not there in a standard multilayer plus metal plate vest.
