Enhanced Bio-morphic Helmet

Michigan Technological University, 2007 - $15,500

Today's standard football helmet design includes a hard outer shell, a protective foam layer, and a comfort foam layer resting on the head. An impact occurring directly to the hard shell is distributed over the padding, which deforms in compression. This works well for direct impacts, protecting against concussion, but doesn't perform as well for indirect or rotational impacts, since the padding is relatively stiff with respect to shear forces.

This E-Team is developing the Enhanced Bio-morphic Helmet (EBM), an improved helmet better able to withstand indirect impacts. The design of the EBM imitates the protection system of the human brain, scalp, skull and cerebrospinal fluid (CSF). The skull is simulated with a composite sandwich shell, the scalp by silicone gel sandwiched between the outer and inner wall of the shell, and the CSF by a soft padding system underneath the inner wall.
