Cellular Structures

Definition

Cellular structures refer to the various components that make up cells, which are the basic units of life. In the context of protective equipment and impact attenuation, understanding cellular structures helps in designing materials that can absorb and dissipate energy during impacts, thereby protecting athletes from injuries. These structures play a crucial role in determining how well a material can respond to force and how effectively it can safeguard the body from trauma.
