发色团是鱼类和头足类动物皮肤中含有色素的细胞，具有变色(变色)和可控的变色(变色)特性。这些动物控制它们皮肤的光学特性来伪装，据推测，也是为了交流。在柔软的人造皮肤结构中复制这些特性的能力为主动伪装、热调节和主动光伏开辟了新的可能性。基于鱼类和头足类动物的皮肤发色团，设计并实现了一种柔软、顺应性的人工发色团。我们展示了由电活性聚合物人工肌肉驱动的人造发色团，模仿了天然发色团中发现的径向定向肌肉。它展示了如何利用介电弹性体结构的面积扩张和通过将有色液体的流体静力转移到人造真皮黑素载体中来实现生物启发的显色。
Chromatophores are the pigment-containing cells in the skins of animals such as fish and cephalopods which have chromomorphic (colour-changing) and controllable goniochromic (iridescent-changing) properties. These animals control the optical properties of their skins for camouflage and, it is speculated, for communication. The ability to replicate these properties in soft artificial skin structures opens up new possibilities for active camouflage, thermal regulation and active photovoltaics. This paper presents the design and implementation of soft and compliant artificial chromatophores based on the cutaneous chromatophores in fish and cephalopods. We demonstrate artificial chromatophores that are actuated by electroactive polymer artificial muscles, mimicking the radially orientated muscles found in natural chromatophores. It is shown how bio-inspired chromomorphism may be achieved using both areal expansion of dielectric elastomer structures and by the hydrostatic translocation of pigmented fluid into an artificial dermal melanophore.
