Jean-François Létard, dirigeant d’OliKrom, présente une innovation issue de la recherche sur des matériaux intelligents capables de changer de couleur selon leur environnement. Ancien chercheur au CNRS, il crée son entreprise pour combler l’écart entre laboratoire et industrie. En collaboration avec Eiffage, OliKrom développe LuminoKrom™, une peinture routière photoluminescente améliorant la sécurité nocturne sans électricité ni émissions de CO₂. Soutenu par l’ADEME, le projet a équipé de nombreuses infrastructures en France et à l’international. Cette innovation illustre l’importance de la coopération, de l’audace et du regard neuf dans les transitions futures pour les mobilités durables et les infrastructures de demain.
Jean-François Létard, CEO of OliKrom, presents an innovation derived from research on smart materials that change color in response to environmental stimuli. A former CNRS researcher, he founded the company to bridge the gap between laboratories and industrial needs. Working with Eiffage, OliKrom developed LuminoKrom™, a photoluminescent road marking paint enhancing nighttime safety without electricity or CO₂ emissions. Supported by ADEME, the project has equipped numerous infrastructures in France and abroad. This example highlights how collaboration, boldness, and fresh perspectives drive sustainable mobility and future infrastructure development across territories facing energy, climate, and safety challenges worldwide today and tomorrow globally.
