| Barrier foils protect organic light-emitting diodes (OLEDs), solar cells, and circuits against water vapor ingress that impact device lifetime. In combination with an artificial intelligence model, a hyperspectral imaging technique developed in Germany promises to dramatically speed up the inspection of those films and streamline industrial production.
