AI Technical Summary
Technical Problem
Users of vehicles are uncertain about the cleanliness of high-touch surfaces despite disinfection efforts, posing concerns for disease transmission due to the lack of visible indication of sanitation status.
Method used
A coating system using chromic materials with core-shell nanoparticles that change optical states from clear to colored or photoemissive upon contact with a cleaning composition, allowing visible indication of sanitation status under illumination.
Benefits of technology
Provides a clear and reversible visual indication of surface cleanliness, ensuring users can confirm sanitation status effectively, maintaining the altered state for at least 30 minutes and potentially longer.
