A Deformable element

摘要

A deformable element (100) comprising a deformable structure (115) and a shear thinning material (113) within the deformable structure. The deformable structure comprises one or more holes (112) through which the shear thinning material will exit the deformable structure and thereby allow deformation of the deformable element upon application of greater than a predetermined level of mechanical shock to the deformable element
