01 Overview
A method for fabricating elastic photopolymer lattices with integrated volumetric holograms whose Bragg condition shifts with strain — producing reversible color changes that visually encode mechanical state. The provisional was filed through the University of Washington's CoMotion tech-transfer office in April 2026.

02 What it does
The lattice combines two normally-incompatible properties: the large reversible strain of an elastomeric photopolymer, and the narrow-band wavelength selectivity of a volume hologram. By tuning lattice geometry, the device can be designed to indicate strain thresholds (color flips at a specific load), strain field maps (color gradient across a deformation), or fatigue accumulation (irreversible color drift).
