新型變形材料模仿章魚偽裝術
New shape-shifting material mimics octopus camouflage
在2026年初，研究人員取得了一項突破，創造出一種能模擬章魚卓越偽裝能力的「軟性光子皮膚」。
In early 2026, researchers made a breakthrough by creating a 'soft photonic skin' that mimics the remarkable camouflage of octopuses.
這些頭足類動物是偽裝大師，牠們利用稱為色素細胞（色ㄙㄜˋ素ㄙㄨˋ細ㄒㄧˋ胞ㄅㄠ）的專用皮膚細胞來改變顏色，並使用稱為乳突（ㄖㄨˇ突ㄊㄨˊ）的肌肉器官來改變紋理。
These cephalopods are masters of disguise, using specialized skin cells called [chromatophores|biological] to change color and muscular organs known as [papillae|biological] to alter their texture.
雖然2017年的早期模型依賴氣動系統來產生3D形狀，但新材料使用了可膨脹聚合物（ㄐㄩˋㄏㄜˊㄨˋ）作為基底。
While earlier 2017 models relied on air-based pneumatic systems to create 3D shapes, the new material uses a [swellable polymer|technological] base.
透過一種稱為電子束微影（ㄉㄧㄢˋㄗˇ束ㄕㄨˋ微ㄨㄟˊ影ㄧㄥˇ）的高精度方法，科學家可以對材料進行程式設計，使其以不同的速率膨脹，在幾秒鐘內將平坦表面轉變為複雜且凹凸不平的地形。
By employing a high-precision method called [electron-beam lithography|technological], scientists can program the material to swell at different rates, transforming a flat surface into a complex, rugged topography in seconds.
此外，這種皮膚利用法布-珀羅諧振器（法ㄈㄚˇ布ㄅㄨˋ-珀ㄆㄛˋ羅ㄌㄨㄛˊ諧ㄒㄧㄝˊ振ㄓㄣˋ器ㄑㄧˋ）透過在聚合物改變尺寸時反射不同波長的光線來轉換顏色。
Additionally, the skin uses [Fabry-Pérot resonators|technological] to shift colors by reflecting different light wavelengths as the polymer changes size.
這種從靜態材料到4D列印的演進，為適應性偽裝、軟體機器人及先進醫療植入物等領域帶來了巨大的前景。
This evolution from static materials to 4D printing holds immense promise for fields like adaptive camouflage, soft robotics, and advanced medical implants.
儘管我們目前還無法比擬真正章魚那種有機的、神經驅動的協調能力，但這些合成創新代表了向我們自身技術實現自主、即時適應邁出了一大步。
While we cannot yet match the organic, neural-powered coordination of an actual octopus, these synthetic innovations represent a massive leap toward autonomous, real-time adaptation in our own technology.
