Switchable Printed Multilayer Devices (C1.3)

Project C1.3 focuses on integrating responsive materials into inkjet-printed multilayer stacks to enable switchable optical properties. Building on prior success with Bragg mirrors and interference filters, the project targets applications such as smart windows for energy-efficient buildings, mid-size displays, and spectrometers using electrically switchable filters. Promising materials include electrochromic, photo-responsive, and liquid-crystalline systems. Key challenges involve printable transparent electrodes, interface design, and seamless integration into multilayer architectures to achieve dynamic control of transmission, reflection, and emission.
