Abstract: Protective gear such as a helmet includes multiple layers including an outer ball bearing layer and/or one or more energy and impact transformer layers. The ball bearing layer exposes multiple ball bearings on the outer surface of the protective gear to deflect and diminish shear forces and other rotational forces imparted onto the outer surface. In many examples, the ball bearings on the outer surface prevent the transfer of shear and rotational forces from the surface of a helmet onto a skull. The energy and impact transformer layers may also include various structures and materials used to dissipate mechanical energy applied to an outer layer or outer shell layer.
