研究、創新與創業 Research, Innovation and Entrepreneurship 35 3D 納米打印邁向新紀元 Stepping into a new era of nanoscale 3D printing 隱形斗篷魔法的創新應用 Developing novel applications for the magical invisibility cloak Professor Chen Shih-Chi and his team from the Department of Mechanical and Automation Engineering, in collaboration with Professor Zhao Ni from the Department of Electronic Engineering and Professor Zhao Yongxin from Carnegie Mellon University, developed a 3D nanofabrication platform that, for the first time, allows for the fabrication of a great variety of materials at a record-setting resolution and a speed much faster than that of the conventional serial fabrication systems currently used in the commercial world. The method simultaneously achieved all key metrics in manufacturing, and can be used to make micro- and nanodevices not previously possible, at high throughput and low cost, with practical applications in photonics, health, automobiles and even aerospace. Artificial optical metamaterials can bend light rays around an object, leading to the invention of the sort of invisibility cloak that used to be the preserve solely of fantasy literature. A research team led by Professor Xu Lei at the Department of Physics, in collaboration with scientists from the mainland, developed the technology further, inventing a first-of-its-kind multifunctional metamaterial device that integrates the technology behind the invisibility cloak with a concentrator and rotator, offering potential applications in cell and tissue culture, and creating new possibilities for the advancement of tissue engineering and drug delivery. 機械與自動化工程學系陳世祈教授及其團 隊，與電子工程學系趙鈮教授及卡內基梅隆 大學招泳欣教授合作，研發嶄新3D納米製 造平台，首次實現多種材料納米結構製造， 以創紀錄的精細度及較傳統商用製造系統更 快的速度，實現用各類材料打印。新技術能 滿足所有製造業的關鍵指標，不但可用於製 造以前不可能產生的微型和納米設備，更具 有高產量和低成本的優點，適用於光子學、 健康、汽車甚至航天領域。 特殊設計的光學材料可扭曲光線，令光線繞 過物體，使物體恍如隱形，實現了魔幻小說中 的可讓人瞬間消失的隱形斗篷。物理系教授 徐磊教授帶領的團隊聯同內地科學家，成功 開發全球首個集隱形、聚集、旋轉等功能於 一體的超材料裝置，有望用於開發新型細胞 和生物組織培養裝置，為組織工程及藥物遞 送技術帶來新方向。
