Vitalshield-OG is a structured composite of carbon-fiber-reinforced polymer and a dense living tissue layer — a BioForge-engineered dermis analog seeded with clotting proteins, regenerative stem-cell clusters, and a capillary network that draws metabolic energy from the wearer's own circulatory system via subcutaneous interface points. Damage to the outer carbon-polymer layer triggers the tissue layer beneath to begin laying down new structural polymer precursors, with full minor-damage repair cycling in 8-16 hours during rest periods. It is the closest thing to biological armor that current materials science can produce.
