Abstract

A trauma mitigation device (100) is provided which includes, an enclosure having a fluid impervious barrier (120), a crushable matrix (150) disposed within said enclosure, and a viscous fluid disposed within said enclosure. Both the matrix and the fluid absorb energy when subjected to an impact force. A composition to be used in the device is also provided. The composition includes a viscous fluid in an amount of about 60-80 % by weight of the composition and a plurality of macrosphere particles, in an amount of about 20-40 % by weight of the total composition, disposed within said viscous fluid.
