Body Armor Shape Sensing Using Fiber Bragg Gratings

This paper explores a new method developed for body armor testing using Fiber Bragg Gratings as the main sensing element for dynamic shape sensing. This will be used to help address injuries that result from armor deformation known as blunt force trauma. Tests were done with projectiles at speeds of up to 420+ m/s and the resulting displacement from the shape sensing algorithm produced profiles with errors less than 10% of the actual shape.
