내용
Nature's dynamic coloration mechanisms, as seen in cephalopods and chameleons, offer a model for high-resolution, adaptive optical systems. Synthetic counterparts have advanced through soft photonic materials driven by various stimuli, yet key challenges remain in achieving fast, localized, and programmable color modulation within scalable architectures. Here, we present a multilayered dielectric elastomer actuator (DEA)-driven photonic array inspired by the hierarchical skin structure of cephalopods. By stacking DEA-photonic units in separate vertical layers, our architecture eliminates lateral mechanical interference, enabling densely packed, independently addressable pixel arrays with a theoretical 100% fill factor. A custom high-voltage multiplexing circuit enables sequential actuation of each layer from a single high voltage (HV) source. Our system demonstrates reconfigurable pattern rendering and synchronized multimodal output including optical and acoustic responses.
