Scientists at the Technical University of Denmark have developed a new way to integrate ultra-thin oxide membranes onto flexible metallic supports, paving the way for next-generation wearable sensors, foldable displays, and flexible energy devices. Their study demonstrates that, by carefully choosing the supporting metal surface, these fragile crystalline sheets can adhere strongly while maintaining their ability to stretch and bend.
“The main finding of this study is the successful integration and adhesion of freestanding single-crystalline oxide membranes—thin crystalline sheets that are detached from their original growth surface—onto metallic titanium nitride (TiN)-coated flexible polymer substrates,” Professor Dae-Sung Park, one of…
