Abstract
A mechanical chameleon through dynamic real-time plasmonic tuning, the external surface of which is covered by plasmonic cells is provided. Plasmonic cells, based on the combination of bimetallic nanodot arrays and electrochemical bias, use the electrochemical method elctrodepositing and stripping Ag shells on plasmonic Au nanodomes and then we achieve the reversible full color plasmonic cells/display. Plasmonic cells, under the control of circuits and sensors, make mechanical chameleon automatically change the color of its own when it's walking to the corresponding background color and always keeping the same color with the color background. This mechanical chameleon through dynamic real-time plasmonic tuning can capture and simulate the entire color-patterns of the environment and then drive the color-changing process in individual cells, fully merging the mechanical chameleon into the surroundings, which makes this technology is readily approachable.
