development of camouflage methods, often through a general
resemblance to the background, has recently become a subject of intense
research. However, an artificial, active camouflage that provides
fast response to color change in the full-visible range for rapid
background matching remains a daunting challenge. To this end, we
report a method, based on the combination of bimetallic nanodot arrays
and electrochemical bias, to allow for plasmonic modulation. Importantly,
our approach permits real-time light manipulation readily matchable
to the color setting in a given environment. We utilize this capability
to fabricate a biomimetic mechanical chameleon and an active matrix
display with dynamic color rendering covering almost the entire visible
region.
