Micro-pixellated blue/brown color changing surface using magnetically actuated nanocomposite actuators

We propose a new magnetically tunable color changing material and its operation method which enable both color generation and change within a single material. To achieve this, we fabricated micro-sized magnetic nanocomposite actuators for a single color changing unit and assembled them on the substrate. This method offers very simple fabrication and operation of color changing surface with high resolution.
