【CAS雙語科學】蛋黃也能“安然無恙”？章魚仿生吸盤來救場
實驗室里，一只機械臂慢慢伸向碗里的生蛋黃。科研人員屏住呼吸，生怕薄薄的蛋黃膜被弄破。然而，機械臂前端的“吸盤”輕輕一貼，一提一放，蛋黃完好無損，連指痕都沒有。
In a laboratory,a robotic arm slowly reached toward a raw egg yolk in a bowl. Researchers held their breath,afraid the delicate yolk membrane would break. Yet the suction cup at the arm's tip gently attached,lifted,and released — the yolk remained intact,without a single mark.

這只“溫柔的手”來自中國科學院蘭州化學物理研究所。團隊研發的國內首款自適應水凝膠仿生吸盤，讓機器人第一次真正學會了“輕拿輕放”。
This"gentle hand"comes from the Lanzhou Institute of Chemical Physics,Chinese Academy of Sciences. The team developed China's first adaptive hydrogel-based bionic suction cup,allowing robots to finally master"gentle grasping".
天生的“黏附大師”
Nature's"Adhesion Master"
章魚的每條腕足上都有成百上千個吸盤，能在濕滑、粗糙甚至多孔的表面牢牢吸附。它們柔軟可變形，像墊圈一樣貼合表面，既穩固又不傷獵物。研究人員希望復制這一“智慧觸感”，讓機器人也能溫柔抓取。
Each of an octopus's arms is covered with hundreds of suction cups that can firmly attach to wet,rough,or porous surfaces. Flexible and deformable,they act like cushions,gripping securely without harming their prey. Researchers aim to replicate this"smart touch",enabling robots to grasp gently.
從果凍到吸盤
From Jelly to Suction Cup
研究人員設計了一種超分子水凝膠，利用強弱氫鍵的配合，讓材料既柔軟又不容易撕裂。然后，他們用3D打印技術打印出帶彎曲薄膜和微小通道的吸盤，實現對不同表面的自適應貼合和溫和吸附。
To achieve this,the team chose hydrogel,a jelly-like soft material that can deform,sense,and recover — ideal for bionic suction cups. They designed a supramolecular hydrogel using strong and weak hydrogen bonds,making it soft yet tear-resistant. With 3D printing,they produced suction cups with curvature membranes and tiny channels,allowing adaptive attachment and gentle grip on various surfaces.

讓機器人學會“溫柔”
Teaching Robots to Be"Gentle"
這款仿生吸盤可以裝在機械臂上，穩穩夾起豆腐、蛋黃等超軟物體而不損傷。它的應用前景廣泛：在深海探測中抓取脆弱生物樣本，在醫療領域用于非侵入性貼附或手術輔助，在柔性制造中搬運精密零件。
This bionic suction cup can be mounted on robotic arms to safely grasp ultra-soft objects like silken tofu or egg yolks. Its potential applications are wide-ranging: collecting fragile samples in deep-sea exploration,non-invasive attachment or surgical assistance in medical settings,and handling delicate parts in flexible manufacturing.
從模仿章魚到超越章魚，這只“柔軟的吸盤”，正在讓機器人變得更聰明，也更溫柔。
From mimicking octopuses to surpassing them,this"soft suction cup"is helping robots become smarter — and gentler.
