Nature highlights ‘retina E-paper’ from Uppsala University in Research Briefing

A popular science follow-up in Nature Research Briefing features a recent Nature article by Kunli Xiong and Satria Santosa from the Department of Materials Science and Engineering. Their research points the way toward the next generation of ultrahigh-resolution, full-colour electronic paper.

Nature has featured Kunli Xiong, Assistant Professor, and Satria Santosa, both from the Department of Materials Science and Engineering, in its Research Briefing section. The article highlights their development of “retina E-paper” – a new type of dynamic nanostructured material that enables ultrahigh-resolution, full-colour electronic displays.

To overcome the resolution limitations of conventional E-paper, the researchers used tungsten trioxide (WO₃) – a classic electrochromic material that can reversibly change its optical state when voltage is applied, even in films only a few hundred nanometres thick. Using advanced nanofabrication, they patterned WO₃ into periodic arrays of nanostructures acting as subpixels within each pixel. This approach allows precise electrical control of colour and brightness, achieving rich colours and ultradense pixels in a single E-paper platform.
