Programmable Optical Megapixel Nanopaper-Cut Matrix
Author:
The team of Jiafang Li and Xiaorong Hong at Beijing Institute of Technology has reported a programmable optical nanoscale origami matrix with pixelated electromechanical reconfigurability. Based on a suspended, angle‑tunable nanoorigami architecture, the authors conceptually designed and experimentally demonstrated a deformable pixel array featuring high duty cycles and strong optical contrast. By leveraging electrostatic forces generated via a central plate and utilizing deformation arms to scatter incident light, they achieved switchable optical encryption and reconfigurable information display by programming a nanoorigami matrix with inter‑pixel spacings of only a few micrometers. Furthermore, employing a bar‑shaped, addressable nanoorigami matrix with 3.87 million pixels, they realized programmable information transmission and optical projection based on line‑level modulation, showcasing an optical microarray with a large pixel count and flexible programmability. Their work realizes highly visible, precisely addressable electromechanical arrays with a large number of pixels, which will significantly enhance the practical utility of miniature optical arrays and open up promising applications in areas such as microdisplays, optoelectronic chips, intelligent machine vision, and hyperspectral imaging sensors.
The research findings were published in Advanced Materials on June 11, 2026, under the title “Programmable Optical Megapixel Nano-Kirigami Matrix.”
