Instrumented Model of the Human Torso for Ballistic Impact

Reference#: P01730

Effective body armor minimizes injury by transferring the kinetic energy of a projectile over an extended time-scale or surface area. Body armor that accomplishes such energy transfer using lightweight materials that are comfortable to wear involves sophisticated technology and engineering. To better assess the quality of new body armor designs, new injury criteria are needed to quantify the damage of different non-penetrating munitions to the internal organs. Therefore there is a need for a human surrogate torso for the purposes of measuring deformation of ribs and the sternum and kinetic energy imparted to organs from different types of non-penetrating munitions.

The Johns Hopkins Applied Physics Laboratory has invented and is patenting an instrumented model of the human torso with simulated anatomic features for measuring the effects of high or low velocity impacts. It includes simulated bone having material properties similar to that of healthy human bone and simulated tissue surrounding the simulated bone. Finally, at least one sensor array is attached to either or both of the simulated bone and the simulated tissue for measuring the effects on the torso of the impacts.
