代替人工 进行 material 体搬运, usually to machine 械臂, it 们 抓手 can light 松拿起我们想 need material 体, fast speed 而准确 放 in in upper. in made as toward can 化转变 当 lower, this type of technology application already 经司空见惯, 不 抓手并不一定都 is machine plant/unit, has plastics can good 搬运工.

　　 day front large aviation aerospace 学院 宋吉舟教授 belt/tape 领 团队提出 一 types new concept, 他们称 its is “万 can 抓手”, can target/goal material 体“锁” in inner, light 松 抓放1 micron to 1米 large small multiple material 体. 不, although is can, this 抓手 组 formed structure complex, its 载体仅仅 is block is “智 can plastics ” 形状记忆 polymer material.

　　形状记忆 polymer is type new type function polymer/macromolecule material, belongs to polymer/macromolecule material research, development, application new separation 支, can tool plastics and features. currently, 形状记忆 polymer already has is application, can material, electronics packaging tube/pipe hot shrinkage film, aviation device solar energy 翻版展开 structure, can device parts and other.

　　 this type of material 神奇之处 in 于, through light, hot and other external can control polymer property 状, can in soft hard between 变换. its to outer force function 时, it can maintain lower deformation degree, again through external conditions its 复原, achieve for material 体 抓取 and 放置.

　　而该项 research positive is 基于此 phenomenon, 科研人员 in 形状记忆 polymer soft/flexible lower, will material or material surface structure its in, again through 转换刺激 conditions, polymer is rigid hard 状态, maintain 嵌入状态 临时形状, from achieve will material 体抓取, rear in formed 转移工 as rear, through again one-time add external 刺激, will polymer to 初始状态, 释放抓取 material 体, this 样就完 formed one-time 搬运. in this process in, as is “抓手” polymer can through 任意改 deformation achieve for different material 体 抓取, 堪称“万 can 锁”.

　　宋吉舟教授 introduction 说, this “万 can 锁” can in type structure material upper generate very large force, 包括球体, block, tube/pipe material 体, 螺栓, 螺母, 枣核, 钥匙串 and other; not only 如此, it also can viscous in material surface, 像壁虎一样, material surface light slip also is coarse 糙.

　　 this type of new methods 也引起 科学家 for/regarding its application areas 兴趣, will material dimensions shrink small to micro degree 观察抓手 搬运效果, in conditions lower, material to surface force, especially is and viscous function strong/high, is material 体 释放 belt/tape more large 挑战.

　　科学家 应 for is, through for polymer surface upper 一层特殊材 material or increase surface coarse degree, decrease low polymer surface viscous force, will material or material surface structure in its internal. this 样一, in 不依赖于 viscous force lower, not only achieve for micro small parts 准确搬运操 as, can very good solution viscous force in material 体释放时 belt/tape 困扰, make is 75 micron large small 不规则 iron pellets or is 直径10 micron oxidation silicon 球, can from 该抓手 upper to 释放.

　　宋吉舟教授 table/sheet 示, in flexible electronics made in, micro device parts fast speed 组装工序十 separation important, made 备基底 upper 数以万计甚至 more more micro nano device parts to flexible use upper. currently commonly used methods is through viscous function achieve for this device parts one-time property 抓取, is 释放 时候 viscous meanwhile formed made factors. in “万 can 抓手” 场景之 lower, micro device parts can viscous function, this research is flexible electronics made provide types new 思路, for/regarding flexible electronics industrial 化进程 has very large 帮助.
