清华大学深圳国际研究生院丁文伯、汪鸿章课题组成功研发出磁驱动液态金属智能抓手1。这一创新装置通过液态金属流动贴合物体表面、遇冷变硬实现抓取、升温后释放的工作原理，能够稳定操控从光滑的玻璃球、粗糙的石头、薄如蝉翼的芯片到细如发丝的针状物等多种物体1。该抓手的理论负载能力超过10千克1。
研究团队通过在镓锡液态金属中引入铁颗粒（GaSn-Fe）实现磁驱动和相变调控1。这项研究成果已发表在国际期刊《器件》（Device）上1，为柔性电子器件操作和精密装配提供了新的技术路径。该项目获得了国家重点研发计划、国家自然科学基金、广东省创新创业研究团队计划、深圳市科技计划等多项资助1。
Researchers at Tsinghua University's Shenzhen International Graduate School have created a magnetically-driven liquid metal gripper capable of handling objects ranging from smooth glass spheres to rough stones, delicate chip components, and hair-thin needles 1. The innovation works by allowing liquid metal to flow and conform to an object's surface, then hardening when cooled to secure the grip before releasing it upon reheating 1.
The team, led by Ding Wenbo and Wang Hongzhang, engineered the device by incorporating iron particles into gallium-tin liquid metal (GaSn-Fe) to enable magnetic actuation and phase-change control 1. The gripper demonstrates theoretical load capacity exceeding 10 kilograms 1. The research findings were published in the international journal Device 1, opening new technological pathways for flexible electronics manipulation and precision assembly applications 1.
The project received support from multiple sources including the National Key Research and Development Program, the National Natural Science Foundation of China, the Guangdong Province Innovation and Entrepreneurship Research Team Program, and the Shenzhen Science and Technology Plan 1.
