🩺 Auxetic Stent — Negative Poisson's Ratio Metamaterial

Deploy two catheter stents lengthwise side by side: an ordinary lattice pinches inward at its ends (positive Poisson's ratio) while a re-entrant bowtie auxetic lattice grows fatter and presses evenly against the vessel wall (negative Poisson's ratio). Live Poisson's-ratio readout and wall-contact-quality comparison.

ControlsDrag the axial stretch slider (or let Auto-deploy animate it) to push both stents to the same deployment length; orbit/zoom the 3D view; watch strut colour (green = wall contact, red = gap) and the live Poisson's-ratio and wall-contact-quality readouts.
