The FlexSheath is a continuous graphene-lattice sheath that encases the entire spinal column without replacing vertebrae, bonding to the periosteum via biocompatible nano-adhesive anchors. The lattice is engineered to absorb and redistribute impact energy across its full surface area, dramatically reducing force transmission to the cord during falls, collisions, and blunt trauma. A secondary piezoelectric layer harvests mechanical energy from movement and powers an embedded posture-correction AI that delivers micro-stimulation to paraspinal muscles to maintain optimal spinal alignment. The sheath flexes naturally with the spine, preserving full range of motion while adding measurable structural protection.

The FlexSheath is Chromeworks' answer to a market gap between clunky industrial replacements and doing nothing at all. It dominates the mid-to-upper professional market — architects, surgeons, athletes, and white-collar workers who spend long hours at screens and want both injury protection and the posture of someone who costs more per hour than you make in a week. The posture-correction feature has become a status signal in Spire boardrooms, where the quiet confidence of a FlexSheath user is recognizable to those in the know.
