Faster, cheaper printing of metal oxide thin film circuits at room temperature

https://techxplore.com/news/2024-08-technique-metal-oxide-thin-circuits.html

"transparent, flexible, robust, high temperatures tolerant circuits (4 nm thick 600° C, 12 nm thick 800°C)... liquid metal oxide meniscus sticks to surface peeling off, exposing liquid on meniscus to air, constantly forming fresh oxide enabling continuous printing of 2-layer 4 nm thick metal oxide film .. films transparent/ highly conductive (films bond with gold preventing core from oxidizing, preserving conductivity over time)... printed metal oxides onto polymer, creating highly flexible circuits surviving 40K foldings"
