A new way to fine-tune exotic materials: Thin, stretch and clamp

Turning a brittle oxide into a flexible membrane and stretching it on a tiny apparatus flipped it from a conducting to an insulating state and changed its magnetic properties. The technique can be used to study and design a broad range of materials for use in things like sensors and detectors. https://www.sciencedaily.com/releases/2020/04/200402144521.htm
