Abstract

Summary In response to the changing environment, chameleons can adjust their skin colors to communicate and create disguise during locomotions. By mimicking their behaviors, we present structural-color actuators that can sense the environment and give responses of non-fatigued vivid color alterations and programmable shape transformations. Due to the sensitive vapochromic and robust vapomechanical response properties, these structural-color actuators exhibit fast color changes (less than 1 s) and non-fatigued shape transformations (more than 110 cycles) when exposed to specific vapors. On the basis of these extraordinary properties, we demonstrate the actuation processes of a rotating pinwheel and a closing/blooming flower with brilliant color changes, and a worm-like structural-color walker that can move forward straight and rhythmically with dynamic color changes. With these chameleon-like behaviors, these structural-color actuators could have important implications in sensing, communication, and disguise of soft robotics.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
