This tiny thermal barcode flips invisible heat like pixels—and opens a door to something far bigger

A Carnegie Mellon University research team has developed a pioneering technology that manipulates thermal radiation with the precision of pixels. The work, published in Science Advances, outlines a method for "digitizing heat," allowing for the intelligent, high-speed, and continuous control of thermal emission. This breakthrough holds significant promise for applications ranging from advanced thermal camouflage to chemical sensing.
